Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522164, here are decompositions:

61 + 31522103 = 31522164
73 + 31522091 = 31522164
103 + 31522061 = 31522164
151 + 31522013 = 31522164
173 + 31521991 = 31522164
211 + 31521953 = 31522164
277 + 31521887 = 31522164
281 + 31521883 = 31522164

Showing the first eight; more decompositions exist.
