Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33613812, here are decompositions:

5 + 33613807 = 33613812
31 + 33613781 = 33613812
61 + 33613751 = 33613812
73 + 33613739 = 33613812
101 + 33613711 = 33613812
131 + 33613681 = 33613812
151 + 33613661 = 33613812
191 + 33613621 = 33613812

Showing the first eight; more decompositions exist.
