Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180022, here are decompositions:

  • 23 + 179999 = 180022
  • 41 + 179981 = 180022
  • 53 + 179969 = 180022
  • 71 + 179951 = 180022
  • 83 + 179939 = 180022
  • 113 + 179909 = 180022
  • 173 + 179849 = 180022
  • 389 + 179633 = 180022

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 180,022 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 180022 first appears in π at position 495,625 of the decimal expansion (the 495,625ordinal-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.
