Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100242, here are decompositions:

5 + 100237 = 100242
29 + 100213 = 100242
53 + 100189 = 100242
59 + 100183 = 100242
73 + 100169 = 100242
89 + 100153 = 100242
113 + 100129 = 100242
139 + 100103 = 100242

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 100,242 and was likely granted around 1870.

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