Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613840, here are decompositions:

11 + 33613829 = 33613840
23 + 33613817 = 33613840
59 + 33613781 = 33613840
83 + 33613757 = 33613840
89 + 33613751 = 33613840
101 + 33613739 = 33613840
179 + 33613661 = 33613840
263 + 33613577 = 33613840

Showing the first eight; more decompositions exist.
