Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483224, here are decompositions:

7 + 31483217 = 31483224
11 + 31483213 = 31483224
61 + 31483163 = 31483224
107 + 31483117 = 31483224
127 + 31483097 = 31483224
131 + 31483093 = 31483224
137 + 31483087 = 31483224
163 + 31483061 = 31483224

Showing the first eight; more decompositions exist.
