Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483402, here are decompositions:

11 + 31483391 = 31483402
89 + 31483313 = 31483402
173 + 31483229 = 31483402
233 + 31483169 = 31483402
239 + 31483163 = 31483402
563 + 31482839 = 31483402
569 + 31482833 = 31483402
641 + 31482761 = 31483402

Showing the first eight; more decompositions exist.
