Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990910, here are decompositions:

  • 17 + 990893 = 990910
  • 23 + 990887 = 990910
  • 29 + 990881 = 990910
  • 59 + 990851 = 990910
  • 101 + 990809 = 990910
  • 113 + 990797 = 990910
  • 149 + 990761 = 990910
  • 191 + 990719 = 990910

Showing the first eight; more decompositions exist.

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 990,910 and was likely granted around 1911.

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

Position in π

The digit sequence 990910 first appears in π at position 332,630 of the decimal expansion (the 332,630ordinal-suffix:th 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.
