Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 104978, here are decompositions:

7 + 104971 = 104978
19 + 104959 = 104978
31 + 104947 = 104978
61 + 104917 = 104978
67 + 104911 = 104978
109 + 104869 = 104978
127 + 104851 = 104978
151 + 104827 = 104978

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 104.978 and was likely granted around 1870.

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