Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31626150, here are decompositions:

19 + 31626131 = 31626150
41 + 31626109 = 31626150
71 + 31626079 = 31626150
97 + 31626053 = 31626150
109 + 31626041 = 31626150
131 + 31626019 = 31626150
139 + 31626011 = 31626150
163 + 31625987 = 31626150

Showing the first eight; more decompositions exist.
