Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604610, here are decompositions:

7 + 31604603 = 31604610
53 + 31604557 = 31604610
101 + 31604509 = 31604610
109 + 31604501 = 31604610
113 + 31604497 = 31604610
157 + 31604453 = 31604610
223 + 31604387 = 31604610
227 + 31604383 = 31604610

Showing the first eight; more decompositions exist.
