Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100798, here are decompositions:

  • 11 + 100787 = 100798
  • 29 + 100769 = 100798
  • 149 + 100649 = 100798
  • 239 + 100559 = 100798
  • 251 + 100547 = 100798
  • 281 + 100517 = 100798
  • 419 + 100379 = 100798
  • 647 + 100151 = 100798

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 100,798 and was likely granted around 1870.

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