Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 130620, here are decompositions:

31 + 130589 = 130620
41 + 130579 = 130620
67 + 130553 = 130620
73 + 130547 = 130620
89 + 130531 = 130620
97 + 130523 = 130620
103 + 130517 = 130620
107 + 130513 = 130620

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 130,620 and was likely granted around 1872.

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