Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180922, here are decompositions:

  • 149 + 180773 = 180922
  • 173 + 180749 = 180922
  • 191 + 180731 = 180922
  • 293 + 180629 = 180922
  • 353 + 180569 = 180922
  • 359 + 180563 = 180922
  • 383 + 180539 = 180922
  • 389 + 180533 = 180922

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 180,922 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 180922 first appears in π at position 749,590 of the decimal expansion (the 749,590ordinal-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.
