Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105030, here are decompositions:

7 + 105023 = 105030
11 + 105019 = 105030
31 + 104999 = 105030
43 + 104987 = 105030
59 + 104971 = 105030
71 + 104959 = 105030
83 + 104947 = 105030
97 + 104933 = 105030

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 105,030 and was likely granted around 1870.

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