Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483246, here are decompositions:

17 + 31483229 = 31483246
29 + 31483217 = 31483246
83 + 31483163 = 31483246
149 + 31483097 = 31483246
269 + 31482977 = 31483246
467 + 31482779 = 31483246
503 + 31482743 = 31483246
563 + 31482683 = 31483246

Showing the first eight; more decompositions exist.
