Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130960, here are decompositions:

  • 3 + 130957 = 130960
  • 101 + 130859 = 130960
  • 131 + 130829 = 130960
  • 149 + 130811 = 130960
  • 173 + 130787 = 130960
  • 191 + 130769 = 130960
  • 311 + 130649 = 130960
  • 317 + 130643 = 130960

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 130,960 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 130960 first appears in π at position 744,143 of the decimal expansion (the 744,143ordinal-suffix:rd 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.
