Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615324, here are decompositions:

3 + 31615321 = 31615324
11 + 31615313 = 31615324
107 + 31615217 = 31615324
113 + 31615211 = 31615324
131 + 31615193 = 31615324
137 + 31615187 = 31615324
197 + 31615127 = 31615324
227 + 31615097 = 31615324

Showing the first eight; more decompositions exist.
