Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103842, here are decompositions:

5 + 103837 = 103842
29 + 103813 = 103842
31 + 103811 = 103842
41 + 103801 = 103842
73 + 103769 = 103842
139 + 103703 = 103842
173 + 103669 = 103842
191 + 103651 = 103842

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 103 842 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.
