Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613978, here are decompositions:

59 + 33613919 = 33613978
131 + 33613847 = 33613978
137 + 33613841 = 33613978
149 + 33613829 = 33613978
197 + 33613781 = 33613978
227 + 33613751 = 33613978
239 + 33613739 = 33613978
317 + 33613661 = 33613978

Showing the first eight; more decompositions exist.
