Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532224, here are decompositions:

5 + 31532219 = 31532224
83 + 31532141 = 31532224
107 + 31532117 = 31532224
257 + 31531967 = 31532224
293 + 31531931 = 31532224
557 + 31531667 = 31532224
701 + 31531523 = 31532224
821 + 31531403 = 31532224

Showing the first eight; more decompositions exist.
