Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31522192, here are decompositions:

11 + 31522181 = 31522192
89 + 31522103 = 31522192
101 + 31522091 = 31522192
131 + 31522061 = 31522192
173 + 31522019 = 31522192
179 + 31522013 = 31522192
239 + 31521953 = 31522192
479 + 31521713 = 31522192

Showing the first eight; more decompositions exist.
