Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 931400, here are decompositions:

13 + 931387 = 931400
37 + 931363 = 931400
97 + 931303 = 931400
163 + 931237 = 931400
271 + 931129 = 931400
277 + 931123 = 931400
313 + 931087 = 931400
397 + 931003 = 931400

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 931,400 and was likely granted around 1909.

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