Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604814, here are decompositions:

11 + 31604803 = 31604814
47 + 31604767 = 31604814
67 + 31604747 = 31604814
71 + 31604743 = 31604814
83 + 31604731 = 31604814
127 + 31604687 = 31604814
167 + 31604647 = 31604814
173 + 31604641 = 31604814

Showing the first eight; more decompositions exist.
