Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622752, here are decompositions:

11 + 31622741 = 31622752
23 + 31622729 = 31622752
53 + 31622699 = 31622752
59 + 31622693 = 31622752
89 + 31622663 = 31622752
173 + 31622579 = 31622752
233 + 31622519 = 31622752
383 + 31622369 = 31622752

Showing the first eight; more decompositions exist.
