Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102770, here are decompositions:

  • 7 + 102763 = 102770
  • 97 + 102673 = 102770
  • 103 + 102667 = 102770
  • 127 + 102643 = 102770
  • 163 + 102607 = 102770
  • 211 + 102559 = 102770
  • 223 + 102547 = 102770
  • 271 + 102499 = 102770

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 102,770 and was likely granted around 1870.

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