Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617082, here are decompositions:

5 + 31617077 = 31617082
53 + 31617029 = 31617082
59 + 31617023 = 31617082
71 + 31617011 = 31617082
83 + 31616999 = 31617082
131 + 31616951 = 31617082
149 + 31616933 = 31617082
179 + 31616903 = 31617082

Showing the first eight; more decompositions exist.
