Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 149386, here are decompositions:

  • 5 + 149381 = 149386
  • 53 + 149333 = 149386
  • 89 + 149297 = 149386
  • 137 + 149249 = 149386
  • 173 + 149213 = 149386
  • 227 + 149159 = 149386
  • 233 + 149153 = 149386
  • 317 + 149069 = 149386

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 149,386 and was likely granted around 1873.

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