Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130782, here are decompositions:

  • 13 + 130769 = 130782
  • 53 + 130729 = 130782
  • 83 + 130699 = 130782
  • 89 + 130693 = 130782
  • 101 + 130681 = 130782
  • 131 + 130651 = 130782
  • 139 + 130643 = 130782
  • 149 + 130633 = 130782

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 130,782 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 130782 first appears in π at position 754,023 of the decimal expansion (the 754,023ordinal-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.
