Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 160810, here are decompositions:

  • 3 + 160807 = 160810
  • 29 + 160781 = 160810
  • 53 + 160757 = 160810
  • 59 + 160751 = 160810
  • 71 + 160739 = 160810
  • 101 + 160709 = 160810
  • 113 + 160697 = 160810
  • 173 + 160637 = 160810

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 160,810 and was likely granted around 1873.

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

Position in π

The digit sequence 160810 first appears in π at position 247,106 of the decimal expansion (the 247,106ordinal-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.
