Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100038, here are decompositions:

19 + 100019 = 100038
47 + 99991 = 100038
67 + 99971 = 100038
109 + 99929 = 100038
131 + 99907 = 100038
137 + 99901 = 100038
157 + 99881 = 100038
167 + 99871 = 100038

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 100,038 and was likely granted around 1870.

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