Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31617066, here are decompositions:

17 + 31617049 = 31617066
37 + 31617029 = 31617066
43 + 31617023 = 31617066
53 + 31617013 = 31617066
67 + 31616999 = 31617066
79 + 31616987 = 31617066
137 + 31616929 = 31617066
149 + 31616917 = 31617066

Showing the first eight; more decompositions exist.
