Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604700, here are decompositions:

11 + 31604689 = 31604700
13 + 31604687 = 31604700
19 + 31604681 = 31604700
53 + 31604647 = 31604700
59 + 31604641 = 31604700
73 + 31604627 = 31604700
89 + 31604611 = 31604700
97 + 31604603 = 31604700

Showing the first eight; more decompositions exist.
