Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613878, here are decompositions:

17 + 33613861 = 33613878
19 + 33613859 = 33613878
29 + 33613849 = 33613878
31 + 33613847 = 33613878
37 + 33613841 = 33613878
61 + 33613817 = 33613878
71 + 33613807 = 33613878
97 + 33613781 = 33613878

Showing the first eight; more decompositions exist.
