Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561678, here are decompositions:

5 + 33561673 = 33561678
37 + 33561641 = 33561678
67 + 33561611 = 33561678
71 + 33561607 = 33561678
79 + 33561599 = 33561678
107 + 33561571 = 33561678
127 + 33561551 = 33561678
151 + 33561527 = 33561678

Showing the first eight; more decompositions exist.
