Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130736, here are decompositions:

  • 7 + 130729 = 130736
  • 37 + 130699 = 130736
  • 43 + 130693 = 130736
  • 79 + 130657 = 130736
  • 97 + 130639 = 130736
  • 103 + 130633 = 130736
  • 157 + 130579 = 130736
  • 223 + 130513 = 130736

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 130,736 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 130736 first appears in π at position 338,513 of the decimal expansion (the 338,513ordinal-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.
