Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561756, here are decompositions:

5 + 33561751 = 33561756
13 + 33561743 = 33561756
37 + 33561719 = 33561756
83 + 33561673 = 33561756
103 + 33561653 = 33561756
149 + 33561607 = 33561756
157 + 33561599 = 33561756
197 + 33561559 = 33561756

Showing the first eight; more decompositions exist.
