Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 947904, here are decompositions:

11 + 947893 = 947904
31 + 947873 = 947904
43 + 947861 = 947904
47 + 947857 = 947904
53 + 947851 = 947904
71 + 947833 = 947904
101 + 947803 = 947904
131 + 947773 = 947904

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 947,904 and was likely granted around 1909.

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