Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622582, here are decompositions:

3 + 31622579 = 31622582
73 + 31622509 = 31622582
109 + 31622473 = 31622582
193 + 31622389 = 31622582
463 + 31622119 = 31622582
601 + 31621981 = 31622582
619 + 31621963 = 31622582
751 + 31621831 = 31622582

Showing the first eight; more decompositions exist.
