Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 185112, here are decompositions:

  • 13 + 185099 = 185112
  • 23 + 185089 = 185112
  • 41 + 185071 = 185112
  • 43 + 185069 = 185112
  • 61 + 185051 = 185112
  • 113 + 184999 = 185112
  • 163 + 184949 = 185112
  • 199 + 184913 = 185112

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 185,112 and was likely granted around 1875.

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

Position in π

The digit sequence 185112 first appears in π at position 290,305 of the decimal expansion (the 290,305ordinal-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.
