Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 131634, here are decompositions:

  • 7 + 131627 = 131634
  • 17 + 131617 = 131634
  • 23 + 131611 = 131634
  • 43 + 131591 = 131634
  • 53 + 131581 = 131634
  • 73 + 131561 = 131634
  • 127 + 131507 = 131634
  • 137 + 131497 = 131634

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 131,634 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 131634 first appears in π at position 789,386 of the decimal expansion (the 789,386ordinal-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.
