Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522102, here are decompositions:

11 + 31522091 = 31522102
41 + 31522061 = 31522102
83 + 31522019 = 31522102
89 + 31522013 = 31522102
149 + 31521953 = 31522102
239 + 31521863 = 31522102
251 + 31521851 = 31522102
389 + 31521713 = 31522102

Showing the first eight; more decompositions exist.
