Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522108, here are decompositions:

5 + 31522103 = 31522108
17 + 31522091 = 31522108
47 + 31522061 = 31522108
89 + 31522019 = 31522108
131 + 31521977 = 31522108
257 + 31521851 = 31522108
461 + 31521647 = 31522108
467 + 31521641 = 31522108

Showing the first eight; more decompositions exist.
