Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561802, here are decompositions:

3 + 33561799 = 33561802
23 + 33561779 = 33561802
59 + 33561743 = 33561802
83 + 33561719 = 33561802
149 + 33561653 = 33561802
191 + 33561611 = 33561802
251 + 33561551 = 33561802
269 + 33561533 = 33561802

Showing the first eight; more decompositions exist.
