Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 102492, here are decompositions:

  • 11 + 102481 = 102492
  • 31 + 102461 = 102492
  • 41 + 102451 = 102492
  • 59 + 102433 = 102492
  • 83 + 102409 = 102492
  • 163 + 102329 = 102492
  • 191 + 102301 = 102492
  • 193 + 102299 = 102492

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 102,492 and was likely granted around 1870.

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