Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102738, here are decompositions:

  • 37 + 102701 = 102738
  • 59 + 102679 = 102738
  • 61 + 102677 = 102738
  • 71 + 102667 = 102738
  • 127 + 102611 = 102738
  • 131 + 102607 = 102738
  • 151 + 102587 = 102738
  • 179 + 102559 = 102738

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 102,738 and was likely granted around 1870.

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