Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622252, here are decompositions:

73 + 31622179 = 31622252
139 + 31622113 = 31622252
271 + 31621981 = 31622252
373 + 31621879 = 31622252
421 + 31621831 = 31622252
499 + 31621753 = 31622252
601 + 31621651 = 31622252
619 + 31621633 = 31622252

Showing the first eight; more decompositions exist.
