Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31483150, here are decompositions:

53 + 31483097 = 31483150
89 + 31483061 = 31483150
173 + 31482977 = 31483150
311 + 31482839 = 31483150
317 + 31482833 = 31483150
389 + 31482761 = 31483150
443 + 31482707 = 31483150
467 + 31482683 = 31483150

Showing the first eight; more decompositions exist.
