Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561290, here are decompositions:

3 + 33561287 = 33561290
19 + 33561271 = 33561290
97 + 33561193 = 33561290
109 + 33561181 = 33561290
151 + 33561139 = 33561290
211 + 33561079 = 33561290
223 + 33561067 = 33561290
271 + 33561019 = 33561290

Showing the first eight; more decompositions exist.
