Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483330, here are decompositions:

3 + 31483327 = 31483330
17 + 31483313 = 31483330
23 + 31483307 = 31483330
101 + 31483229 = 31483330
113 + 31483217 = 31483330
167 + 31483163 = 31483330
233 + 31483097 = 31483330
269 + 31483061 = 31483330

Showing the first eight; more decompositions exist.
