Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100340, here are decompositions:

7 + 100333 = 100340
43 + 100297 = 100340
61 + 100279 = 100340
73 + 100267 = 100340
103 + 100237 = 100340
127 + 100213 = 100340
151 + 100189 = 100340
157 + 100183 = 100340

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 100,340 and was likely granted around 1870.

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

Possible US bank routing number

This passes the ABA routing number checksum and matches the Federal Reserve numbering scheme.
