Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105480, here are decompositions:

13 + 105467 = 105480
31 + 105449 = 105480
43 + 105437 = 105480
73 + 105407 = 105480
79 + 105401 = 105480
83 + 105397 = 105480
101 + 105379 = 105480
107 + 105373 = 105480

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 105,480 and was likely granted around 1870.

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