Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130814, here are decompositions:

  • 3 + 130811 = 130814
  • 7 + 130807 = 130814
  • 31 + 130783 = 130814
  • 127 + 130687 = 130814
  • 157 + 130657 = 130814
  • 163 + 130651 = 130814
  • 181 + 130633 = 130814
  • 193 + 130621 = 130814

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 130,814 and was likely granted around 1872.

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

Position in π

The digit sequence 130814 first appears in π at position 686,210 of the decimal expansion (the 686,210ordinal-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.
