Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 101902, here are decompositions:

  • 11 + 101891 = 101902
  • 23 + 101879 = 101902
  • 29 + 101873 = 101902
  • 113 + 101789 = 101902
  • 131 + 101771 = 101902
  • 179 + 101723 = 101902
  • 239 + 101663 = 101902
  • 389 + 101513 = 101902

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 101,902 and was likely granted around 1870.

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