Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522038, here are decompositions:

17 + 31522021 = 31522038
19 + 31522019 = 31522038
47 + 31521991 = 31522038
59 + 31521979 = 31522038
61 + 31521977 = 31522038
151 + 31521887 = 31522038
367 + 31521671 = 31522038
389 + 31521649 = 31522038

Showing the first eight; more decompositions exist.
