Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028850, here are decompositions:

  • 7 + 1028843 = 1028850
  • 13 + 1028837 = 1028850
  • 41 + 1028809 = 1028850
  • 47 + 1028803 = 1028850
  • 73 + 1028777 = 1028850
  • 89 + 1028761 = 1028850
  • 101 + 1028749 = 1028850
  • 103 + 1028747 = 1028850

Showing the first eight; more decompositions exist.

Possible date

Could be parsed as a date. Most likely interpretation: Sunday, January 2, 8850 (MDDYYYY (US, single-digit month)).

Other possible interpretations (3)
  • 8850-02-01 (DMMYYYY (Euro, single-digit day))
  • 8850-10-02 (MMDYYYY (US, single-digit day))
  • 8850-02-10 (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 1,028,850 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 1028850 first appears in π at position 21,103 of the decimal expansion (the 21,103ordinal-suffix:rd 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.
