Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 990004, here are decompositions:

3 + 990001 = 990004
5 + 989999 = 990004
23 + 989981 = 990004
53 + 989951 = 990004
83 + 989921 = 990004
131 + 989873 = 990004
167 + 989837 = 990004
173 + 989831 = 990004

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 990,004 and was likely granted around 1911.

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