Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33564780, here are decompositions:

13 + 33564767 = 33564780
19 + 33564761 = 33564780
23 + 33564757 = 33564780
43 + 33564737 = 33564780
101 + 33564679 = 33564780
103 + 33564677 = 33564780
107 + 33564673 = 33564780
127 + 33564653 = 33564780

Showing the first eight; more decompositions exist.
