Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616070, here are decompositions:

11 + 31616059 = 31616070
23 + 31616047 = 31616070
29 + 31616041 = 31616070
37 + 31616033 = 31616070
47 + 31616023 = 31616070
53 + 31616017 = 31616070
61 + 31616009 = 31616070
71 + 31615999 = 31616070

Showing the first eight; more decompositions exist.
