Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622132, here are decompositions:

13 + 31622119 = 31622132
19 + 31622113 = 31622132
151 + 31621981 = 31622132
379 + 31621753 = 31622132
439 + 31621693 = 31622132
463 + 31621669 = 31622132
499 + 31621633 = 31622132
541 + 31621591 = 31622132

Showing the first eight; more decompositions exist.
