Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105898, here are decompositions:

131 + 105767 = 105898
137 + 105761 = 105898
197 + 105701 = 105898
389 + 105509 = 105898
431 + 105467 = 105898
449 + 105449 = 105898
461 + 105437 = 105898
491 + 105407 = 105898

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 105.898 and was likely granted around 1870.

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