Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561742, here are decompositions:

23 + 33561719 = 33561742
89 + 33561653 = 33561742
101 + 33561641 = 33561742
131 + 33561611 = 33561742
191 + 33561551 = 33561742
239 + 33561503 = 33561742
353 + 33561389 = 33561742
479 + 33561263 = 33561742

Showing the first eight; more decompositions exist.
