Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1029100, here are decompositions:

101 + 1028999 = 1029100
131 + 1028969 = 1029100
197 + 1028903 = 1029100
227 + 1028873 = 1029100
257 + 1028843 = 1029100
263 + 1028837 = 1029100
353 + 1028747 = 1029100
419 + 1028681 = 1029100

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 1,029,100 and was likely granted around 1912.

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