Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931900, here are decompositions:

  • 17 + 931883 = 931900
  • 23 + 931877 = 931900
  • 41 + 931859 = 931900
  • 89 + 931811 = 931900
  • 149 + 931751 = 931900
  • 173 + 931727 = 931900
  • 191 + 931709 = 931900
  • 383 + 931517 = 931900

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 931,900 and was likely granted around 1909.

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