Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8667628, here are decompositions:

  • 17 + 8667611 = 8667628
  • 89 + 8667539 = 8667628
  • 107 + 8667521 = 8667628
  • 131 + 8667497 = 8667628
  • 197 + 8667431 = 8667628
  • 251 + 8667377 = 8667628
  • 257 + 8667371 = 8667628
  • 401 + 8667227 = 8667628

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 8,667,628 and was likely granted around 2014.

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