Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622482, here are decompositions:

53 + 31622429 = 31622482
113 + 31622369 = 31622482
293 + 31622189 = 31622482
401 + 31622081 = 31622482
503 + 31621979 = 31622482
743 + 31621739 = 31622482
809 + 31621673 = 31622482
821 + 31621661 = 31622482

Showing the first eight; more decompositions exist.
