Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33591728, here are decompositions:

7 + 33591721 = 33591728
61 + 33591667 = 33591728
109 + 33591619 = 33591728
211 + 33591517 = 33591728
229 + 33591499 = 33591728
439 + 33591289 = 33591728
631 + 33591097 = 33591728
661 + 33591067 = 33591728

Showing the first eight; more decompositions exist.
