Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 940400, here are decompositions:

31 + 940369 = 940400
73 + 940327 = 940400
103 + 940297 = 940400
151 + 940249 = 940400
199 + 940201 = 940400
211 + 940189 = 940400
313 + 940087 = 940400
397 + 940003 = 940400

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 940,400 and was likely granted around 1909.

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