Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 118890, here are decompositions:

17 + 118873 = 118890
29 + 118861 = 118890
47 + 118843 = 118890
59 + 118831 = 118890
71 + 118819 = 118890
89 + 118801 = 118890
103 + 118787 = 118890
139 + 118751 = 118890

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 118,890 and was likely granted around 1871.

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