Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622232, here are decompositions:

43 + 31622189 = 31622232
53 + 31622179 = 31622232
79 + 31622153 = 31622232
101 + 31622131 = 31622232
113 + 31622119 = 31622232
151 + 31622081 = 31622232
251 + 31621981 = 31622232
269 + 31621963 = 31622232

Showing the first eight; more decompositions exist.
