Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 977640, here are decompositions:

  • 11 + 977629 = 977640
  • 29 + 977611 = 977640
  • 31 + 977609 = 977640
  • 47 + 977593 = 977640
  • 73 + 977567 = 977640
  • 101 + 977539 = 977640
  • 127 + 977513 = 977640
  • 193 + 977447 = 977640

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 977,640 and was likely granted around 1910.

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