Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990040, here are decompositions:

3 + 990037 = 990040
17 + 990023 = 990040
41 + 989999 = 990040
59 + 989981 = 990040
89 + 989951 = 990040
101 + 989939 = 990040
131 + 989909 = 990040
167 + 989873 = 990040

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 990,040 and was likely granted around 1911.

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