Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31604616, here are decompositions:

5 + 31604611 = 31604616
7 + 31604609 = 31604616
13 + 31604603 = 31604616
59 + 31604557 = 31604616
83 + 31604533 = 31604616
107 + 31604509 = 31604616
163 + 31604453 = 31604616
229 + 31604387 = 31604616

Showing the first eight; more decompositions exist.
