Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613520, here are decompositions:

37 + 33613483 = 33613520
43 + 33613477 = 33613520
79 + 33613441 = 33613520
181 + 33613339 = 33613520
277 + 33613243 = 33613520
307 + 33613213 = 33613520
349 + 33613171 = 33613520
439 + 33613081 = 33613520

Showing the first eight; more decompositions exist.
