Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616106, here are decompositions:

37 + 31616069 = 31616106
47 + 31616059 = 31616106
59 + 31616047 = 31616106
73 + 31616033 = 31616106
83 + 31616023 = 31616106
89 + 31616017 = 31616106
97 + 31616009 = 31616106
107 + 31615999 = 31616106

Showing the first eight; more decompositions exist.
