Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 137142, here are decompositions:

  • 11 + 137131 = 137142
  • 23 + 137119 = 137142
  • 53 + 137089 = 137142
  • 113 + 137029 = 137142
  • 149 + 136993 = 137142
  • 151 + 136991 = 137142
  • 163 + 136979 = 137142
  • 179 + 136963 = 137142

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 137,142 and was likely granted around 1872.

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