Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33591642, here are decompositions:

5 + 33591637 = 33591642
13 + 33591629 = 33591642
23 + 33591619 = 33591642
89 + 33591553 = 33591642
109 + 33591533 = 33591642
151 + 33591491 = 33591642
173 + 33591469 = 33591642
179 + 33591463 = 33591642

Showing the first eight; more decompositions exist.
