Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622152, here are decompositions:

5 + 31622147 = 31622152
11 + 31622141 = 31622152
71 + 31622081 = 31622152
173 + 31621979 = 31622152
251 + 31621901 = 31622152
449 + 31621703 = 31622152
479 + 31621673 = 31622152
491 + 31621661 = 31622152

Showing the first eight; more decompositions exist.
