Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543224, here are decompositions:

5 + 31543219 = 31543224
7 + 31543217 = 31543224
17 + 31543207 = 31543224
43 + 31543181 = 31543224
61 + 31543163 = 31543224
157 + 31543067 = 31543224
233 + 31542991 = 31543224
257 + 31542967 = 31543224

Showing the first eight; more decompositions exist.
