Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604212, here are decompositions:

23 + 31604189 = 31604212
83 + 31604129 = 31604212
113 + 31604099 = 31604212
179 + 31604033 = 31604212
281 + 31603931 = 31604212
293 + 31603919 = 31604212
383 + 31603829 = 31604212
461 + 31603751 = 31604212

Showing the first eight; more decompositions exist.
