Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8673870, here are decompositions:

  • 31 + 8673839 = 8673870
  • 53 + 8673817 = 8673870
  • 89 + 8673781 = 8673870
  • 109 + 8673761 = 8673870
  • 167 + 8673703 = 8673870
  • 193 + 8673677 = 8673870
  • 269 + 8673601 = 8673870
  • 277 + 8673593 = 8673870

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 8,673,870 and was likely granted around 2014.

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