Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33591640, here are decompositions:

3 + 33591637 = 33591640
11 + 33591629 = 33591640
23 + 33591617 = 33591640
107 + 33591533 = 33591640
113 + 33591527 = 33591640
149 + 33591491 = 33591640
197 + 33591443 = 33591640
239 + 33591401 = 33591640

Showing the first eight; more decompositions exist.
