Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621568, here are decompositions:

131 + 33621437 = 33621568
179 + 33621389 = 33621568
257 + 33621311 = 33621568
269 + 33621299 = 33621568
317 + 33621251 = 33621568
419 + 33621149 = 33621568
521 + 33621047 = 33621568
569 + 33620999 = 33621568

Showing the first eight; more decompositions exist.
