Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180936, here are decompositions:

  • 29 + 180907 = 180936
  • 53 + 180883 = 180936
  • 89 + 180847 = 180936
  • 137 + 180799 = 180936
  • 139 + 180797 = 180936
  • 157 + 180779 = 180936
  • 163 + 180773 = 180936
  • 257 + 180679 = 180936

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 180,936 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 180936 first appears in π at position 69,552 of the decimal expansion (the 69,552ordinal-suffix:nd 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.
