Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604730, here are decompositions:

7 + 31604723 = 31604730
11 + 31604719 = 31604730
41 + 31604689 = 31604730
43 + 31604687 = 31604730
83 + 31604647 = 31604730
89 + 31604641 = 31604730
103 + 31604627 = 31604730
127 + 31604603 = 31604730

Showing the first eight; more decompositions exist.
