Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100548, here are decompositions:

  • 11 + 100537 = 100548
  • 29 + 100519 = 100548
  • 31 + 100517 = 100548
  • 37 + 100511 = 100548
  • 47 + 100501 = 100548
  • 79 + 100469 = 100548
  • 89 + 100459 = 100548
  • 101 + 100447 = 100548

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 100,548 and was likely granted around 1870.

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