Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180950, here are decompositions:

  • 43 + 180907 = 180950
  • 67 + 180883 = 180950
  • 79 + 180871 = 180950
  • 103 + 180847 = 180950
  • 139 + 180811 = 180950
  • 151 + 180799 = 180950
  • 157 + 180793 = 180950
  • 199 + 180751 = 180950

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 180,950 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 180950 first appears in π at position 252,077 of the decimal expansion (the 252,077ordinal-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.
