Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102378, here are decompositions:

  • 11 + 102367 = 102378
  • 19 + 102359 = 102378
  • 41 + 102337 = 102378
  • 61 + 102317 = 102378
  • 79 + 102299 = 102378
  • 127 + 102251 = 102378
  • 137 + 102241 = 102378
  • 149 + 102229 = 102378

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 102,378 and was likely granted around 1870.

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