Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180182, here are decompositions:

  • 3 + 180179 = 180182
  • 109 + 180073 = 180182
  • 139 + 180043 = 180182
  • 181 + 180001 = 180182
  • 193 + 179989 = 180182
  • 229 + 179953 = 180182
  • 283 + 179899 = 180182
  • 349 + 179833 = 180182

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 180,182 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 180182 first appears in π at position 302,634 of the decimal expansion (the 302,634ordinal-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.
