Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8672020, here are decompositions:

  • 17 + 8672003 = 8672020
  • 29 + 8671991 = 8672020
  • 41 + 8671979 = 8672020
  • 53 + 8671967 = 8672020
  • 83 + 8671937 = 8672020
  • 101 + 8671919 = 8672020
  • 113 + 8671907 = 8672020
  • 251 + 8671769 = 8672020

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 8,672,020 and was likely granted around 2014.

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