Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028672, here are decompositions:

  • 3 + 1028669 = 1028672
  • 103 + 1028569 = 1028672
  • 163 + 1028509 = 1028672
  • 193 + 1028479 = 1028672
  • 199 + 1028473 = 1028672
  • 283 + 1028389 = 1028672
  • 409 + 1028263 = 1028672
  • 523 + 1028149 = 1028672

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Tuesday, January 2, 8672 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 8672-02-01 (DMMYYYY (Euro, single-digit day))
  • 8672-10-02 (MMDYYYY (US, single-digit day))
  • 8672-02-10 (DDMYYYY (Euro, single-digit month))
Possible US patent number

This number falls in the range of US utility patent numbers. If it's a patent, it would be issued as US 1,028,672 and was likely granted around 1912.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 1028672 first appears in π at position 965,231 of the decimal expansion (the 965,231ordinal-suffix:st digit after the integer 3).

Search range: the first 1,000,000 fractional digits of π. Any 6-digit-or-shorter string is virtually guaranteed to appear in there — the more interesting signal is the position.
