Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516266, here are decompositions:

13 + 31516253 = 31516266
29 + 31516237 = 31516266
83 + 31516183 = 31516266
107 + 31516159 = 31516266
109 + 31516157 = 31516266
113 + 31516153 = 31516266
127 + 31516139 = 31516266
137 + 31516129 = 31516266

Showing the first eight; more decompositions exist.
