Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617148, here are decompositions:

47 + 31617101 = 31617148
71 + 31617077 = 31617148
137 + 31617011 = 31617148
149 + 31616999 = 31617148
197 + 31616951 = 31617148
257 + 31616891 = 31617148
401 + 31616747 = 31617148
419 + 31616729 = 31617148

Showing the first eight; more decompositions exist.
