Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 991092, here are decompositions:

  • 13 + 991079 = 991092
  • 19 + 991073 = 991092
  • 23 + 991069 = 991092
  • 29 + 991063 = 991092
  • 61 + 991031 = 991092
  • 83 + 991009 = 991092
  • 103 + 990989 = 991092
  • 131 + 990961 = 991092

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 991,092 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 991092 first appears in π at position 887,005 of the decimal expansion (the 887,005ordinal-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.
