Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507864, here are decompositions:

11 + 33507853 = 33507864
43 + 33507821 = 33507864
67 + 33507797 = 33507864
83 + 33507781 = 33507864
101 + 33507763 = 33507864
113 + 33507751 = 33507864
127 + 33507737 = 33507864
193 + 33507671 = 33507864

Showing the first eight; more decompositions exist.
