Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100216, here are decompositions:

3 + 100213 = 100216
23 + 100193 = 100216
47 + 100169 = 100216
107 + 100109 = 100216
113 + 100103 = 100216
167 + 100049 = 100216
173 + 100043 = 100216
197 + 100019 = 100216

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 100,216 and was likely granted around 1870.

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