Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483822, here are decompositions:

3 + 31483819 = 31483822
23 + 31483799 = 31483822
89 + 31483733 = 31483822
131 + 31483691 = 31483822
173 + 31483649 = 31483822
239 + 31483583 = 31483822
269 + 31483553 = 31483822
353 + 31483469 = 31483822

Showing the first eight; more decompositions exist.
