Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604774, here are decompositions:

7 + 31604767 = 31604774
31 + 31604743 = 31604774
43 + 31604731 = 31604774
127 + 31604647 = 31604774
163 + 31604611 = 31604774
241 + 31604533 = 31604774
277 + 31604497 = 31604774
433 + 31604341 = 31604774

Showing the first eight; more decompositions exist.
