Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931398, here are decompositions:

  • 11 + 931387 = 931398
  • 47 + 931351 = 931398
  • 79 + 931319 = 931398
  • 89 + 931309 = 931398
  • 109 + 931289 = 931398
  • 131 + 931267 = 931398
  • 157 + 931241 = 931398
  • 199 + 931199 = 931398

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 931,398 and was likely granted around 1909.

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