Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561618, here are decompositions:

7 + 33561611 = 33561618
11 + 33561607 = 33561618
19 + 33561599 = 33561618
47 + 33561571 = 33561618
59 + 33561559 = 33561618
61 + 33561557 = 33561618
67 + 33561551 = 33561618
149 + 33561469 = 33561618

Showing the first eight; more decompositions exist.
