Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130488, here are decompositions:

  • 5 + 130483 = 130488
  • 11 + 130477 = 130488
  • 19 + 130469 = 130488
  • 31 + 130457 = 130488
  • 41 + 130447 = 130488
  • 79 + 130409 = 130488
  • 89 + 130399 = 130488
  • 109 + 130379 = 130488

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 130,488 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 130488 first appears in π at position 389,512 of the decimal expansion (the 389,512ordinal-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.
