Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31567344, here are decompositions:

31 + 31567313 = 31567344
47 + 31567297 = 31567344
73 + 31567271 = 31567344
103 + 31567241 = 31567344
113 + 31567231 = 31567344
131 + 31567213 = 31567344
191 + 31567153 = 31567344
257 + 31567087 = 31567344

Showing the first eight; more decompositions exist.
