Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33612720, here are decompositions:

13 + 33612707 = 33612720
17 + 33612703 = 33612720
19 + 33612701 = 33612720
23 + 33612697 = 33612720
41 + 33612679 = 33612720
47 + 33612673 = 33612720
109 + 33612611 = 33612720
137 + 33612583 = 33612720

Showing the first eight; more decompositions exist.
