Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561838, here are decompositions:

59 + 33561779 = 33561838
71 + 33561767 = 33561838
197 + 33561641 = 33561838
227 + 33561611 = 33561838
239 + 33561599 = 33561838
281 + 33561557 = 33561838
311 + 33561527 = 33561838
449 + 33561389 = 33561838

Showing the first eight; more decompositions exist.
