Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180854, here are decompositions:

7 + 180847 = 180854
43 + 180811 = 180854
61 + 180793 = 180854
103 + 180751 = 180854
307 + 180547 = 180854
313 + 180541 = 180854
463 + 180391 = 180854
523 + 180331 = 180854

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 180,854 and was likely granted around 1875.

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