Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 183188, here are decompositions:

  • 37 + 183151 = 183188
  • 97 + 183091 = 183188
  • 151 + 183037 = 183188
  • 331 + 182857 = 183188
  • 337 + 182851 = 183188
  • 349 + 182839 = 183188
  • 367 + 182821 = 183188
  • 409 + 182779 = 183188

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 183,188 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 183188 first appears in π at position 650,278 of the decimal expansion (the 650,278ordinal-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.
