Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180564, here are decompositions:

17 + 180547 = 180564
23 + 180541 = 180564
31 + 180533 = 180564
53 + 180511 = 180564
61 + 180503 = 180564
67 + 180497 = 180564
73 + 180491 = 180564
101 + 180463 = 180564

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 180,564 and was likely granted around 1875.

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