Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021154, here are decompositions:

31 + 1021123 = 1021154
61 + 1021093 = 1021154
67 + 1021087 = 1021154
73 + 1021081 = 1021154
157 + 1020997 = 1021154
163 + 1020991 = 1021154
181 + 1020973 = 1021154
193 + 1020961 = 1021154

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 1,021,154 and was likely granted around 1912.

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