Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8662920, here are decompositions:

  • 29 + 8662891 = 8662920
  • 31 + 8662889 = 8662920
  • 53 + 8662867 = 8662920
  • 61 + 8662859 = 8662920
  • 67 + 8662853 = 8662920
  • 89 + 8662831 = 8662920
  • 109 + 8662811 = 8662920
  • 113 + 8662807 = 8662920

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 8,662,920 and was likely granted around 2014.

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