Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100028, here are decompositions:

37 + 99991 = 100028
67 + 99961 = 100028
127 + 99901 = 100028
151 + 99877 = 100028
157 + 99871 = 100028
199 + 99829 = 100028
211 + 99817 = 100028
241 + 99787 = 100028

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 100,028 and was likely granted around 1870.

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