Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1051242, here are decompositions:

61 + 1051181 = 1051242
89 + 1051153 = 1051242
103 + 1051139 = 1051242
163 + 1051079 = 1051242
173 + 1051069 = 1051242
191 + 1051051 = 1051242
223 + 1051019 = 1051242
233 + 1051009 = 1051242

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 1,051,242 and was likely granted around 1912.

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