Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 105272, here are decompositions:

3 + 105269 = 105272
19 + 105253 = 105272
43 + 105229 = 105272
61 + 105211 = 105272
73 + 105199 = 105272
241 + 105031 = 105272
313 + 104959 = 105272
421 + 104851 = 105272

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 105.272 and was likely granted around 1870.

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