Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 100120, here are decompositions:

11 + 100109 = 100120
17 + 100103 = 100120
71 + 100049 = 100120
101 + 100019 = 100120
131 + 99989 = 100120
149 + 99971 = 100120
191 + 99929 = 100120
197 + 99923 = 100120

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 100,120 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.
