Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522132, here are decompositions:

3 + 31522129 = 31522132
29 + 31522103 = 31522132
41 + 31522091 = 31522132
71 + 31522061 = 31522132
113 + 31522019 = 31522132
179 + 31521953 = 31522132
269 + 31521863 = 31522132
281 + 31521851 = 31522132

Showing the first eight; more decompositions exist.
