Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483244, here are decompositions:

7 + 31483237 = 31483244
31 + 31483213 = 31483244
127 + 31483117 = 31483244
151 + 31483093 = 31483244
157 + 31483087 = 31483244
193 + 31483051 = 31483244
241 + 31483003 = 31483244
271 + 31482973 = 31483244

Showing the first eight; more decompositions exist.
