Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604342, here are decompositions:

31 + 31604311 = 31604342
43 + 31604299 = 31604342
61 + 31604281 = 31604342
79 + 31604263 = 31604342
151 + 31604191 = 31604342
409 + 31603933 = 31604342
463 + 31603879 = 31604342
499 + 31603843 = 31604342

Showing the first eight; more decompositions exist.
