Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33624720, here are decompositions:

13 + 33624707 = 33624720
23 + 33624697 = 33624720
37 + 33624683 = 33624720
79 + 33624641 = 33624720
109 + 33624611 = 33624720
113 + 33624607 = 33624720
137 + 33624583 = 33624720
149 + 33624571 = 33624720

Showing the first eight; more decompositions exist.
