Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31508046, here are decompositions:

7 + 31508039 = 31508046
19 + 31508027 = 31508046
29 + 31508017 = 31508046
43 + 31508003 = 31508046
107 + 31507939 = 31508046
149 + 31507897 = 31508046
223 + 31507823 = 31508046
257 + 31507789 = 31508046

Showing the first eight; more decompositions exist.
