Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561810, here are decompositions:

11 + 33561799 = 33561810
31 + 33561779 = 33561810
41 + 33561769 = 33561810
43 + 33561767 = 33561810
59 + 33561751 = 33561810
67 + 33561743 = 33561810
131 + 33561679 = 33561810
137 + 33561673 = 33561810

Showing the first eight; more decompositions exist.
