Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617162, here are decompositions:

13 + 31617149 = 31617162
29 + 31617133 = 31617162
61 + 31617101 = 31617162
89 + 31617073 = 31617162
113 + 31617049 = 31617162
139 + 31617023 = 31617162
149 + 31617013 = 31617162
151 + 31617011 = 31617162

Showing the first eight; more decompositions exist.
