Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990030, here are decompositions:

7 + 990023 = 990030
17 + 990013 = 990030
29 + 990001 = 990030
31 + 989999 = 990030
53 + 989977 = 990030
59 + 989971 = 990030
71 + 989959 = 990030
79 + 989951 = 990030

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 990,030 and was likely granted around 1911.

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