Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604706, here are decompositions:

17 + 31604689 = 31604706
19 + 31604687 = 31604706
59 + 31604647 = 31604706
79 + 31604627 = 31604706
97 + 31604609 = 31604706
103 + 31604603 = 31604706
149 + 31604557 = 31604706
173 + 31604533 = 31604706

Showing the first eight; more decompositions exist.
