Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617150, here are decompositions:

17 + 31617133 = 31617150
73 + 31617077 = 31617150
101 + 31617049 = 31617150
127 + 31617023 = 31617150
137 + 31617013 = 31617150
139 + 31617011 = 31617150
151 + 31616999 = 31617150
163 + 31616987 = 31617150

Showing the first eight; more decompositions exist.
