Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33564778, here are decompositions:

11 + 33564767 = 33564778
17 + 33564761 = 33564778
41 + 33564737 = 33564778
47 + 33564731 = 33564778
101 + 33564677 = 33564778
227 + 33564551 = 33564778
419 + 33564359 = 33564778
647 + 33564131 = 33564778

Showing the first eight; more decompositions exist.
