Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615296, here are decompositions:

23 + 31615273 = 31615296
59 + 31615237 = 31615296
67 + 31615229 = 31615296
79 + 31615217 = 31615296
103 + 31615193 = 31615296
109 + 31615187 = 31615296
127 + 31615169 = 31615296
199 + 31615097 = 31615296

Showing the first eight; more decompositions exist.
