Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103880, here are decompositions:

  • 13 + 103867 = 103880
  • 37 + 103843 = 103880
  • 43 + 103837 = 103880
  • 67 + 103813 = 103880
  • 79 + 103801 = 103880
  • 157 + 103723 = 103880
  • 181 + 103699 = 103880
  • 193 + 103687 = 103880

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 103,880 and was likely granted around 1870.

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