Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561690, here are decompositions:

11 + 33561679 = 33561690
17 + 33561673 = 33561690
37 + 33561653 = 33561690
79 + 33561611 = 33561690
83 + 33561607 = 33561690
131 + 33561559 = 33561690
139 + 33561551 = 33561690
157 + 33561533 = 33561690

Showing the first eight; more decompositions exist.
