Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8700190, here are decompositions:

  • 29 + 8700161 = 8700190
  • 131 + 8700059 = 8700190
  • 179 + 8700011 = 8700190
  • 197 + 8699993 = 8700190
  • 311 + 8699879 = 8700190
  • 383 + 8699807 = 8700190
  • 419 + 8699771 = 8700190
  • 467 + 8699723 = 8700190

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 8,700,190 and was likely granted around 2014.

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