Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33591688, here are decompositions:

5 + 33591683 = 33591688
29 + 33591659 = 33591688
41 + 33591647 = 33591688
47 + 33591641 = 33591688
59 + 33591629 = 33591688
71 + 33591617 = 33591688
191 + 33591497 = 33591688
197 + 33591491 = 33591688

Showing the first eight; more decompositions exist.
