Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522150, here are decompositions:

47 + 31522103 = 31522150
59 + 31522091 = 31522150
89 + 31522061 = 31522150
131 + 31522019 = 31522150
137 + 31522013 = 31522150
173 + 31521977 = 31522150
197 + 31521953 = 31522150
263 + 31521887 = 31522150

Showing the first eight; more decompositions exist.
