Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617184, here are decompositions:

3 + 31617181 = 31617184
17 + 31617167 = 31617184
83 + 31617101 = 31617184
107 + 31617077 = 31617184
173 + 31617011 = 31617184
197 + 31616987 = 31617184
233 + 31616951 = 31617184
251 + 31616933 = 31617184

Showing the first eight; more decompositions exist.
