Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31605654, here are decompositions:

61 + 31605593 = 31605654
71 + 31605583 = 31605654
83 + 31605571 = 31605654
97 + 31605557 = 31605654
103 + 31605551 = 31605654
137 + 31605517 = 31605654
163 + 31605491 = 31605654
211 + 31605443 = 31605654

Showing the first eight; more decompositions exist.
