Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931538, here are decompositions:

  • 151 + 931387 = 931538
  • 229 + 931309 = 931538
  • 271 + 931267 = 931538
  • 409 + 931129 = 931538
  • 547 + 930991 = 931538
  • 607 + 930931 = 931538
  • 691 + 930847 = 931538
  • 919 + 930619 = 931538

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 931,538 and was likely granted around 1909.

Patent numbers below 100,000 are excluded as too ambiguous; modern numbering currently reaches roughly 12.5 million.

Position in π

The digit sequence 931538 first appears in π at position 240,159 of the decimal expansion (the 240,159ordinal-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.
