Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522080, here are decompositions:

19 + 31522061 = 31522080
59 + 31522021 = 31522080
61 + 31522019 = 31522080
67 + 31522013 = 31522080
89 + 31521991 = 31522080
101 + 31521979 = 31522080
103 + 31521977 = 31522080
127 + 31521953 = 31522080

Showing the first eight; more decompositions exist.
