Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613578, here are decompositions:

7 + 33613571 = 33613578
17 + 33613561 = 33613578
29 + 33613549 = 33613578
41 + 33613537 = 33613578
79 + 33613499 = 33613578
101 + 33613477 = 33613578
109 + 33613469 = 33613578
137 + 33613441 = 33613578

Showing the first eight; more decompositions exist.
