Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 156626, here are decompositions:

  • 3 + 156623 = 156626
  • 7 + 156619 = 156626
  • 37 + 156589 = 156626
  • 139 + 156487 = 156626
  • 307 + 156319 = 156626
  • 367 + 156259 = 156626
  • 373 + 156253 = 156626
  • 397 + 156229 = 156626

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 156,626 and was likely granted around 1873.

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