Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568332, here are decompositions:

23 + 31568309 = 31568332
311 + 31568021 = 31568332
401 + 31567931 = 31568332
449 + 31567883 = 31568332
563 + 31567769 = 31568332
659 + 31567673 = 31568332
683 + 31567649 = 31568332
773 + 31567559 = 31568332

Showing the first eight; more decompositions exist.
