Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33561636, here are decompositions:

29 + 33561607 = 33561636
37 + 33561599 = 33561636
79 + 33561557 = 33561636
103 + 33561533 = 33561636
109 + 33561527 = 33561636
167 + 33561469 = 33561636
223 + 33561413 = 33561636
257 + 33561379 = 33561636

Showing the first eight; more decompositions exist.
