Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483222, here are decompositions:

5 + 31483217 = 31483222
53 + 31483169 = 31483222
59 + 31483163 = 31483222
383 + 31482839 = 31483222
389 + 31482833 = 31483222
401 + 31482821 = 31483222
443 + 31482779 = 31483222
461 + 31482761 = 31483222

Showing the first eight; more decompositions exist.
