Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130668, here are decompositions:

  • 11 + 130657 = 130668
  • 17 + 130651 = 130668
  • 19 + 130649 = 130668
  • 29 + 130639 = 130668
  • 37 + 130631 = 130668
  • 47 + 130621 = 130668
  • 79 + 130589 = 130668
  • 89 + 130579 = 130668

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 130,668 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 130668 first appears in π at position 662,395 of the decimal expansion (the 662,395ordinal-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.
