Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617124, here are decompositions:

23 + 31617101 = 31617124
47 + 31617077 = 31617124
101 + 31617023 = 31617124
113 + 31617011 = 31617124
137 + 31616987 = 31617124
173 + 31616951 = 31617124
191 + 31616933 = 31617124
233 + 31616891 = 31617124

Showing the first eight; more decompositions exist.
