Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567304, here are decompositions:

7 + 31567297 = 31567304
37 + 31567267 = 31567304
73 + 31567231 = 31567304
151 + 31567153 = 31567304
331 + 31566973 = 31567304
337 + 31566967 = 31567304
487 + 31566817 = 31567304
541 + 31566763 = 31567304

Showing the first eight; more decompositions exist.
