Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990130, here are decompositions:

107 + 990023 = 990130
131 + 989999 = 990130
149 + 989981 = 990130
179 + 989951 = 990130
191 + 989939 = 990130
257 + 989873 = 990130
293 + 989837 = 990130
347 + 989783 = 990130

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 990,130 and was likely granted around 1911.

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