Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8687070, here are decompositions:

  • 43 + 8687027 = 8687070
  • 71 + 8686999 = 8687070
  • 89 + 8686981 = 8687070
  • 109 + 8686961 = 8687070
  • 181 + 8686889 = 8687070
  • 193 + 8686877 = 8687070
  • 229 + 8686841 = 8687070
  • 241 + 8686829 = 8687070

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 8,687,070 and was likely granted around 2014.

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