Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158472, here are decompositions:

  • 23 + 158449 = 158472
  • 29 + 158443 = 158472
  • 43 + 158429 = 158472
  • 53 + 158419 = 158472
  • 79 + 158393 = 158472
  • 101 + 158371 = 158472
  • 109 + 158363 = 158472
  • 113 + 158359 = 158472

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 158,472 and was likely granted around 1873.

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