Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 146688, here are decompositions:

  • 5 + 146683 = 146688
  • 7 + 146681 = 146688
  • 11 + 146677 = 146688
  • 19 + 146669 = 146688
  • 41 + 146647 = 146688
  • 71 + 146617 = 146688
  • 79 + 146609 = 146688
  • 107 + 146581 = 146688

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 146,688 and was likely granted around 1873.

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