Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 187102, here are decompositions:

11 + 187091 = 187102
29 + 187073 = 187102
53 + 187049 = 187102
59 + 187043 = 187102
233 + 186869 = 187102
359 + 186743 = 187102
401 + 186701 = 187102
431 + 186671 = 187102

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 187,102 and was likely granted around 1875.

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