Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100578, here are decompositions:

19 + 100559 = 100578
29 + 100549 = 100578
31 + 100547 = 100578
41 + 100537 = 100578
59 + 100519 = 100578
61 + 100517 = 100578
67 + 100511 = 100578
109 + 100469 = 100578

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 100,578 and was likely granted around 1870.

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