Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616148, here are decompositions:

19 + 31616129 = 31616148
79 + 31616069 = 31616148
89 + 31616059 = 31616148
101 + 31616047 = 31616148
107 + 31616041 = 31616148
127 + 31616021 = 31616148
131 + 31616017 = 31616148
139 + 31616009 = 31616148

Showing the first eight; more decompositions exist.
