Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561566, here are decompositions:

7 + 33561559 = 33561566
97 + 33561469 = 33561566
223 + 33561343 = 33561566
373 + 33561193 = 33561566
397 + 33561169 = 33561566
463 + 33561103 = 33561566
487 + 33561079 = 33561566
499 + 33561067 = 33561566

Showing the first eight; more decompositions exist.
