Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670042, here are decompositions:

  • 5 + 8670037 = 8670042
  • 11 + 8670031 = 8670042
  • 13 + 8670029 = 8670042
  • 53 + 8669989 = 8670042
  • 61 + 8669981 = 8670042
  • 79 + 8669963 = 8670042
  • 103 + 8669939 = 8670042
  • 113 + 8669929 = 8670042

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 8,670,042 and was likely granted around 2014.

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