Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561812, here are decompositions:

13 + 33561799 = 33561812
43 + 33561769 = 33561812
61 + 33561751 = 33561812
139 + 33561673 = 33561812
241 + 33561571 = 33561812
433 + 33561379 = 33561812
541 + 33561271 = 33561812
619 + 33561193 = 33561812

Showing the first eight; more decompositions exist.
