Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022646, here are decompositions:

  • 7 + 1022639 = 1022646
  • 13 + 1022633 = 1022646
  • 17 + 1022629 = 1022646
  • 73 + 1022573 = 1022646
  • 127 + 1022519 = 1022646
  • 137 + 1022509 = 1022646
  • 139 + 1022507 = 1022646
  • 179 + 1022467 = 1022646

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Friday, January 2, 2646 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 2646-02-01 (DMMYYYY (Euro, single-digit day))
  • 2646-10-02 (MMDYYYY (US, single-digit day))
  • 2646-02-10 (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 1,022,646 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 1022646 first appears in π at position 191,621 of the decimal expansion (the 191,621ordinal-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.
