Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33581628, here are decompositions:

7 + 33581621 = 33581628
11 + 33581617 = 33581628
29 + 33581599 = 33581628
107 + 33581521 = 33581628
137 + 33581491 = 33581628
191 + 33581437 = 33581628
277 + 33581351 = 33581628
307 + 33581321 = 33581628

Showing the first eight; more decompositions exist.
