Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 182772, here are decompositions:

  • 59 + 182713 = 182772
  • 61 + 182711 = 182772
  • 71 + 182701 = 182772
  • 113 + 182659 = 182772
  • 131 + 182641 = 182772
  • 173 + 182599 = 182772
  • 179 + 182593 = 182772
  • 193 + 182579 = 182772

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 182,772 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 182772 first appears in π at position 832,795 of the decimal expansion (the 832,795ordinal-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.
