Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100472, here are decompositions:

  • 3 + 100469 = 100472
  • 13 + 100459 = 100472
  • 61 + 100411 = 100472
  • 79 + 100393 = 100472
  • 109 + 100363 = 100472
  • 139 + 100333 = 100472
  • 181 + 100291 = 100472
  • 193 + 100279 = 100472

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 100,472 and was likely granted around 1870.

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