Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1005154, here are decompositions:

11 + 1005143 = 1005154
23 + 1005131 = 1005154
47 + 1005107 = 1005154
53 + 1005101 = 1005154
83 + 1005071 = 1005154
113 + 1005041 = 1005154
167 + 1004987 = 1005154
173 + 1004981 = 1005154

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 1,005,154 and was likely granted around 1911.

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