Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31615344, here are decompositions:

11 + 31615333 = 31615344
23 + 31615321 = 31615344
31 + 31615313 = 31615344
71 + 31615273 = 31615344
107 + 31615237 = 31615344
127 + 31615217 = 31615344
151 + 31615193 = 31615344
157 + 31615187 = 31615344

Showing the first eight; more decompositions exist.
