Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604358, here are decompositions:

11 + 31604347 = 31604358
17 + 31604341 = 31604358
47 + 31604311 = 31604358
59 + 31604299 = 31604358
61 + 31604297 = 31604358
131 + 31604227 = 31604358
139 + 31604219 = 31604358
167 + 31604191 = 31604358

Showing the first eight; more decompositions exist.
