Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 138082, here are decompositions:

  • 3 + 138079 = 138082
  • 5 + 138077 = 138082
  • 11 + 138071 = 138082
  • 23 + 138059 = 138082
  • 29 + 138053 = 138082
  • 41 + 138041 = 138082
  • 83 + 137999 = 138082
  • 89 + 137993 = 138082

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 138,082 and was likely granted around 1872.

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