Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621448, here are decompositions:

11 + 33621437 = 33621448
41 + 33621407 = 33621448
59 + 33621389 = 33621448
137 + 33621311 = 33621448
149 + 33621299 = 33621448
197 + 33621251 = 33621448
401 + 33621047 = 33621448
449 + 33620999 = 33621448

Showing the first eight; more decompositions exist.
