Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156874, here are decompositions:

  • 41 + 156833 = 156874
  • 167 + 156707 = 156874
  • 191 + 156683 = 156874
  • 197 + 156677 = 156874
  • 233 + 156641 = 156874
  • 251 + 156623 = 156874
  • 281 + 156593 = 156874
  • 353 + 156521 = 156874

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 156,874 and was likely granted around 1873.

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