Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 109000, here are decompositions:

  • 29 + 108971 = 109000
  • 41 + 108959 = 109000
  • 53 + 108947 = 109000
  • 71 + 108929 = 109000
  • 83 + 108917 = 109000
  • 107 + 108893 = 109000
  • 113 + 108887 = 109000
  • 131 + 108869 = 109000

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 109,000 and was likely granted around 1871.

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