Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105784, here are decompositions:

  • 17 + 105767 = 105784
  • 23 + 105761 = 105784
  • 83 + 105701 = 105784
  • 101 + 105683 = 105784
  • 131 + 105653 = 105784
  • 227 + 105557 = 105784
  • 251 + 105533 = 105784
  • 257 + 105527 = 105784

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 105,784 and was likely granted around 1870.

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