Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100456, here are decompositions:

53 + 100403 = 100456
113 + 100343 = 100456
263 + 100193 = 100456
347 + 100109 = 100456
353 + 100103 = 100456
467 + 99989 = 100456
617 + 99839 = 100456
647 + 99809 = 100456

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 100,456 and was likely granted around 1870.

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