Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483338, here are decompositions:

11 + 31483327 = 31483338
31 + 31483307 = 31483338
101 + 31483237 = 31483338
109 + 31483229 = 31483338
241 + 31483097 = 31483338
251 + 31483087 = 31483338
269 + 31483069 = 31483338
277 + 31483061 = 31483338

Showing the first eight; more decompositions exist.
