Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 980640, here are decompositions:

  • 19 + 980621 = 980640
  • 41 + 980599 = 980640
  • 47 + 980593 = 980640
  • 53 + 980587 = 980640
  • 61 + 980579 = 980640
  • 83 + 980557 = 980640
  • 137 + 980503 = 980640
  • 149 + 980491 = 980640

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 980,640 and was likely granted around 1910.

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