Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700040, here are decompositions:

  • 3 + 8700037 = 8700040
  • 29 + 8700011 = 8700040
  • 47 + 8699993 = 8700040
  • 59 + 8699981 = 8700040
  • 71 + 8699969 = 8700040
  • 227 + 8699813 = 8700040
  • 233 + 8699807 = 8700040
  • 269 + 8699771 = 8700040

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 8,700,040 and was likely granted around 2014.

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