Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483498, here are decompositions:

5 + 31483493 = 31483498
29 + 31483469 = 31483498
41 + 31483457 = 31483498
107 + 31483391 = 31483498
191 + 31483307 = 31483498
269 + 31483229 = 31483498
281 + 31483217 = 31483498
401 + 31483097 = 31483498

Showing the first eight; more decompositions exist.
