Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165892, here are decompositions:

  • 5 + 165887 = 165892
  • 59 + 165833 = 165892
  • 113 + 165779 = 165892
  • 173 + 165719 = 165892
  • 179 + 165713 = 165892
  • 191 + 165701 = 165892
  • 239 + 165653 = 165892
  • 281 + 165611 = 165892

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 165,892 and was likely granted around 1874.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 165892 first appears in π at position 85,250 of the decimal expansion (the 85,250ordinal-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.
