Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31516296, here are decompositions:

43 + 31516253 = 31516296
59 + 31516237 = 31516296
107 + 31516189 = 31516296
113 + 31516183 = 31516296
137 + 31516159 = 31516296
139 + 31516157 = 31516296
157 + 31516139 = 31516296
167 + 31516129 = 31516296

Showing the first eight; more decompositions exist.
