Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483318, here are decompositions:

5 + 31483313 = 31483318
11 + 31483307 = 31483318
89 + 31483229 = 31483318
101 + 31483217 = 31483318
149 + 31483169 = 31483318
257 + 31483061 = 31483318
479 + 31482839 = 31483318
557 + 31482761 = 31483318

Showing the first eight; more decompositions exist.
