Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561612, here are decompositions:

5 + 33561607 = 33561612
13 + 33561599 = 33561612
41 + 33561571 = 33561612
53 + 33561559 = 33561612
61 + 33561551 = 33561612
79 + 33561533 = 33561612
109 + 33561503 = 33561612
199 + 33561413 = 33561612

Showing the first eight; more decompositions exist.
