Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180372, here are decompositions:

  • 11 + 180361 = 180372
  • 41 + 180331 = 180372
  • 61 + 180311 = 180372
  • 83 + 180289 = 180372
  • 109 + 180263 = 180372
  • 113 + 180259 = 180372
  • 131 + 180241 = 180372
  • 139 + 180233 = 180372

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 180,372 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 180372 first appears in π at position 132,655 of the decimal expansion (the 132,655ordinal-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.
