Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130756, here are decompositions:

  • 107 + 130649 = 130756
  • 113 + 130643 = 130756
  • 137 + 130619 = 130756
  • 167 + 130589 = 130756
  • 233 + 130523 = 130756
  • 239 + 130517 = 130756
  • 317 + 130439 = 130756
  • 347 + 130409 = 130756

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 130,756 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 130756 first appears in π at position 228,043 of the decimal expansion (the 228,043ordinal-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.
