Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615366, here are decompositions:

23 + 31615343 = 31615366
53 + 31615313 = 31615366
137 + 31615229 = 31615366
149 + 31615217 = 31615366
173 + 31615193 = 31615366
179 + 31615187 = 31615366
197 + 31615169 = 31615366
239 + 31615127 = 31615366

Showing the first eight; more decompositions exist.
