Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 152700, here are decompositions:

19 + 152681 = 152700
29 + 152671 = 152700
43 + 152657 = 152700
59 + 152641 = 152700
61 + 152639 = 152700
71 + 152629 = 152700
83 + 152617 = 152700
101 + 152599 = 152700

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 152,700 and was likely granted around 1873.

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