Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180392, here are decompositions:

  • 13 + 180379 = 180392
  • 31 + 180361 = 180392
  • 61 + 180331 = 180392
  • 103 + 180289 = 180392
  • 151 + 180241 = 180392
  • 181 + 180211 = 180392
  • 211 + 180181 = 180392
  • 349 + 180043 = 180392

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 180,392 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 180392 first appears in π at position 415,541 of the decimal expansion (the 415,541ordinal-suffix:st 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.
