Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613640, here are decompositions:

3 + 33613637 = 33613640
19 + 33613621 = 33613640
43 + 33613597 = 33613640
79 + 33613561 = 33613640
103 + 33613537 = 33613640
157 + 33613483 = 33613640
163 + 33613477 = 33613640
199 + 33613441 = 33613640

Showing the first eight; more decompositions exist.
