Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621454, here are decompositions:

17 + 33621437 = 33621454
47 + 33621407 = 33621454
71 + 33621383 = 33621454
281 + 33621173 = 33621454
563 + 33620891 = 33621454
641 + 33620813 = 33621454
773 + 33620681 = 33621454
827 + 33620627 = 33621454

Showing the first eight; more decompositions exist.
