Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105438, here are decompositions:

31 + 105407 = 105438
37 + 105401 = 105438
41 + 105397 = 105438
59 + 105379 = 105438
71 + 105367 = 105438
79 + 105359 = 105438
97 + 105341 = 105438
101 + 105337 = 105438

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 105.438 and was likely granted around 1870.

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