Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700042, here are decompositions:

  • 5 + 8700037 = 8700042
  • 11 + 8700031 = 8700042
  • 23 + 8700019 = 8700042
  • 31 + 8700011 = 8700042
  • 41 + 8700001 = 8700042
  • 61 + 8699981 = 8700042
  • 73 + 8699969 = 8700042
  • 83 + 8699959 = 8700042

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 8,700,042 and was likely granted around 2014.

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