Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103620, here are decompositions:

  • 7 + 103613 = 103620
  • 29 + 103591 = 103620
  • 37 + 103583 = 103620
  • 43 + 103577 = 103620
  • 47 + 103573 = 103620
  • 53 + 103567 = 103620
  • 59 + 103561 = 103620
  • 67 + 103553 = 103620

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 103,620 and was likely granted around 1870.

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