Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 121116, here are decompositions:

  • 53 + 121063 = 121116
  • 97 + 121019 = 121116
  • 103 + 121013 = 121116
  • 109 + 121007 = 121116
  • 139 + 120977 = 121116
  • 173 + 120943 = 121116
  • 179 + 120937 = 121116
  • 197 + 120919 = 121116

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 121,116 and was likely granted around 1871.

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

Position in π

The digit sequence 121116 first appears in π at position 121,988 of the decimal expansion (the 121,988ordinal-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.
