Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622652, here are decompositions:

11 + 31622641 = 31622652
23 + 31622629 = 31622652
53 + 31622599 = 31622652
73 + 31622579 = 31622652
179 + 31622473 = 31622652
223 + 31622429 = 31622652
263 + 31622389 = 31622652
283 + 31622369 = 31622652

Showing the first eight; more decompositions exist.
