Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 951640, here are decompositions:

  • 3 + 951637 = 951640
  • 17 + 951623 = 951640
  • 59 + 951581 = 951640
  • 83 + 951557 = 951640
  • 149 + 951491 = 951640
  • 191 + 951449 = 951640
  • 227 + 951413 = 951640
  • 233 + 951407 = 951640

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 951,640 and was likely granted around 1909.

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