Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31456252, here are decompositions:

5 + 31456247 = 31456252
11 + 31456241 = 31456252
53 + 31456199 = 31456252
59 + 31456193 = 31456252
89 + 31456163 = 31456252
131 + 31456121 = 31456252
173 + 31456079 = 31456252
239 + 31456013 = 31456252

Showing the first eight; more decompositions exist.
