Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31623150, here are decompositions:

29 + 31623121 = 31623150
37 + 31623113 = 31623150
89 + 31623061 = 31623150
103 + 31623047 = 31623150
109 + 31623041 = 31623150
127 + 31623023 = 31623150
191 + 31622959 = 31623150
199 + 31622951 = 31623150

Showing the first eight; more decompositions exist.
