Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31616154, here are decompositions:

5 + 31616149 = 31616154
41 + 31616113 = 31616154
107 + 31616047 = 31616154
113 + 31616041 = 31616154
131 + 31616023 = 31616154
137 + 31616017 = 31616154
181 + 31615973 = 31616154
233 + 31615921 = 31616154

Showing the first eight; more decompositions exist.
