Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 181314, here are decompositions:

  • 11 + 181303 = 181314
  • 13 + 181301 = 181314
  • 17 + 181297 = 181314
  • 31 + 181283 = 181314
  • 37 + 181277 = 181314
  • 41 + 181273 = 181314
  • 61 + 181253 = 181314
  • 71 + 181243 = 181314

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 181,314 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 181314 first appears in π at position 322,201 of the decimal expansion (the 322,201ordinal-suffix:st 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.
