Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 162816, here are decompositions:

  • 29 + 162787 = 162816
  • 37 + 162779 = 162816
  • 67 + 162749 = 162816
  • 89 + 162727 = 162816
  • 103 + 162713 = 162816
  • 107 + 162709 = 162816
  • 113 + 162703 = 162816
  • 139 + 162677 = 162816

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 162,816 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 162816 first appears in π at position 697,027 of the decimal expansion (the 697,027ordinal-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.
