Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617112, here are decompositions:

11 + 31617101 = 31617112
83 + 31617029 = 31617112
89 + 31617023 = 31617112
101 + 31617011 = 31617112
113 + 31616999 = 31617112
179 + 31616933 = 31617112
383 + 31616729 = 31617112
419 + 31616693 = 31617112

Showing the first eight; more decompositions exist.
