Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 165896, here are decompositions:

  • 13 + 165883 = 165896
  • 19 + 165877 = 165896
  • 67 + 165829 = 165896
  • 79 + 165817 = 165896
  • 97 + 165799 = 165896
  • 193 + 165703 = 165896
  • 223 + 165673 = 165896
  • 229 + 165667 = 165896

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 165,896 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 165896 first appears in π at position 65,862 of the decimal expansion (the 65,862ordinal-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.
