Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931240, here are decompositions:

  • 3 + 931237 = 931240
  • 41 + 931199 = 931240
  • 47 + 931193 = 931240
  • 59 + 931181 = 931240
  • 71 + 931169 = 931240
  • 113 + 931127 = 931240
  • 173 + 931067 = 931240
  • 227 + 931013 = 931240

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 931,240 and was likely granted around 1909.

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