Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 180070, here are decompositions:

17 + 180053 = 180070
47 + 180023 = 180070
71 + 179999 = 180070
89 + 179981 = 180070
101 + 179969 = 180070
113 + 179957 = 180070
131 + 179939 = 180070
167 + 179903 = 180070

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 180,070 and was likely granted around 1875.

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