Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483922, here are decompositions:

3 + 31483919 = 31483922
61 + 31483861 = 31483922
103 + 31483819 = 31483922
163 + 31483759 = 31483922
199 + 31483723 = 31483922
373 + 31483549 = 31483922
571 + 31483351 = 31483922
661 + 31483261 = 31483922

Showing the first eight; more decompositions exist.
