Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604670, here are decompositions:

23 + 31604647 = 31604670
29 + 31604641 = 31604670
43 + 31604627 = 31604670
59 + 31604611 = 31604670
61 + 31604609 = 31604670
67 + 31604603 = 31604670
109 + 31604561 = 31604670
113 + 31604557 = 31604670

Showing the first eight; more decompositions exist.
