Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 157000, here are decompositions:

29 + 156971 = 157000
59 + 156941 = 157000
101 + 156899 = 157000
113 + 156887 = 157000
167 + 156833 = 157000
251 + 156749 = 157000
281 + 156719 = 157000
293 + 156707 = 157000

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 157,000 and was likely granted around 1873.

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