Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102902, here are decompositions:

  • 31 + 102871 = 102902
  • 43 + 102859 = 102902
  • 61 + 102841 = 102902
  • 73 + 102829 = 102902
  • 109 + 102793 = 102902
  • 139 + 102763 = 102902
  • 223 + 102679 = 102902
  • 229 + 102673 = 102902

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 102,902 and was likely granted around 1870.

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