Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31622786, here are decompositions:

7 + 31622779 = 31622786
43 + 31622743 = 31622786
73 + 31622713 = 31622786
103 + 31622683 = 31622786
157 + 31622629 = 31622786
277 + 31622509 = 31622786
313 + 31622473 = 31622786
397 + 31622389 = 31622786

Showing the first eight; more decompositions exist.
