Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561772, here are decompositions:

3 + 33561769 = 33561772
5 + 33561767 = 33561772
29 + 33561743 = 33561772
53 + 33561719 = 33561772
131 + 33561641 = 33561772
173 + 33561599 = 33561772
239 + 33561533 = 33561772
269 + 33561503 = 33561772

Showing the first eight; more decompositions exist.
