Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483248, here are decompositions:

11 + 31483237 = 31483248
19 + 31483229 = 31483248
31 + 31483217 = 31483248
79 + 31483169 = 31483248
131 + 31483117 = 31483248
151 + 31483097 = 31483248
179 + 31483069 = 31483248
197 + 31483051 = 31483248

Showing the first eight; more decompositions exist.
