Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617042, here are decompositions:

13 + 31617029 = 31617042
19 + 31617023 = 31617042
29 + 31617013 = 31617042
31 + 31617011 = 31617042
43 + 31616999 = 31617042
109 + 31616933 = 31617042
113 + 31616929 = 31617042
139 + 31616903 = 31617042

Showing the first eight; more decompositions exist.
