Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 158520, here are decompositions:

13 + 158507 = 158520
31 + 158489 = 158520
71 + 158449 = 158520
101 + 158419 = 158520
113 + 158407 = 158520
127 + 158393 = 158520
149 + 158371 = 158520
157 + 158363 = 158520

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 158,520 and was likely granted around 1873.

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