Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100874, here are decompositions:

73 + 100801 = 100874
127 + 100747 = 100874
181 + 100693 = 100874
283 + 100591 = 100874
337 + 100537 = 100874
373 + 100501 = 100874
457 + 100417 = 100874
463 + 100411 = 100874

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 100,874 and was likely granted around 1870.

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