Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 170142, here are decompositions:

  • 19 + 170123 = 170142
  • 31 + 170111 = 170142
  • 41 + 170101 = 170142
  • 43 + 170099 = 170142
  • 61 + 170081 = 170142
  • 79 + 170063 = 170142
  • 113 + 170029 = 170142
  • 139 + 170003 = 170142

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 170,142 and was likely granted around 1874.

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