Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561658, here are decompositions:

5 + 33561653 = 33561658
17 + 33561641 = 33561658
47 + 33561611 = 33561658
59 + 33561599 = 33561658
101 + 33561557 = 33561658
107 + 33561551 = 33561658
131 + 33561527 = 33561658
269 + 33561389 = 33561658

Showing the first eight; more decompositions exist.
