Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 163738, here are decompositions:

  • 5 + 163733 = 163738
  • 41 + 163697 = 163738
  • 59 + 163679 = 163738
  • 101 + 163637 = 163738
  • 137 + 163601 = 163738
  • 251 + 163487 = 163738
  • 257 + 163481 = 163738
  • 269 + 163469 = 163738

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 163,738 and was likely granted around 1874.

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