Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617204, here are decompositions:

5 + 31617199 = 31617204
23 + 31617181 = 31617204
37 + 31617167 = 31617204
71 + 31617133 = 31617204
103 + 31617101 = 31617204
127 + 31617077 = 31617204
131 + 31617073 = 31617204
181 + 31617023 = 31617204

Showing the first eight; more decompositions exist.
