Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103740, here are decompositions:

  • 17 + 103723 = 103740
  • 37 + 103703 = 103740
  • 41 + 103699 = 103740
  • 53 + 103687 = 103740
  • 59 + 103681 = 103740
  • 71 + 103669 = 103740
  • 83 + 103657 = 103740
  • 89 + 103651 = 103740

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 103,740 and was likely granted around 1870.

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