Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931940, here are decompositions:

  • 7 + 931933 = 931940
  • 19 + 931921 = 931940
  • 67 + 931873 = 931940
  • 103 + 931837 = 931940
  • 151 + 931789 = 931940
  • 157 + 931783 = 931940
  • 193 + 931747 = 931940
  • 211 + 931729 = 931940

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 931,940 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 931940 first appears in π at position 186,340 of the decimal expansion (the 186,340ordinal-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.
