Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131184, here are decompositions:

  • 13 + 131171 = 131184
  • 41 + 131143 = 131184
  • 71 + 131113 = 131184
  • 73 + 131111 = 131184
  • 83 + 131101 = 131184
  • 113 + 131071 = 131184
  • 173 + 131011 = 131184
  • 197 + 130987 = 131184

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 131,184 and was likely granted around 1872.

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

Position in π

The digit sequence 131184 first appears in π at position 66,268 of the decimal expansion (the 66,268ordinal-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.
