Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8670142, here are decompositions:

  • 53 + 8670089 = 8670142
  • 71 + 8670071 = 8670142
  • 101 + 8670041 = 8670142
  • 113 + 8670029 = 8670142
  • 149 + 8669993 = 8670142
  • 179 + 8669963 = 8670142
  • 263 + 8669879 = 8670142
  • 281 + 8669861 = 8670142

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 8,670,142 and was likely granted around 2014.

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