Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604826, here are decompositions:

23 + 31604803 = 31604826
37 + 31604789 = 31604826
59 + 31604767 = 31604826
67 + 31604759 = 31604826
79 + 31604747 = 31604826
83 + 31604743 = 31604826
103 + 31604723 = 31604826
107 + 31604719 = 31604826

Showing the first eight; more decompositions exist.
