Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 153040, here are decompositions:

47 + 152993 = 153040
59 + 152981 = 153040
101 + 152939 = 153040
131 + 152909 = 153040
197 + 152843 = 153040
257 + 152783 = 153040
263 + 152777 = 153040
311 + 152729 = 153040

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 153,040 and was likely granted around 1873.

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