Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616082, here are decompositions:

13 + 31616069 = 31616082
23 + 31616059 = 31616082
41 + 31616041 = 31616082
59 + 31616023 = 31616082
61 + 31616021 = 31616082
73 + 31616009 = 31616082
83 + 31615999 = 31616082
89 + 31615993 = 31616082

Showing the first eight; more decompositions exist.
