Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33591620, here are decompositions:

3 + 33591617 = 33591620
67 + 33591553 = 33591620
103 + 33591517 = 33591620
151 + 33591469 = 33591620
157 + 33591463 = 33591620
193 + 33591427 = 33591620
211 + 33591409 = 33591620
277 + 33591343 = 33591620

Showing the first eight; more decompositions exist.
