Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616088, here are decompositions:

19 + 31616069 = 31616088
29 + 31616059 = 31616088
41 + 31616047 = 31616088
47 + 31616041 = 31616088
67 + 31616021 = 31616088
71 + 31616017 = 31616088
79 + 31616009 = 31616088
89 + 31615999 = 31616088

Showing the first eight; more decompositions exist.
