Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621690, here are decompositions:

17 + 33621673 = 33621690
29 + 33621661 = 33621690
41 + 33621649 = 33621690
61 + 33621629 = 33621690
79 + 33621611 = 33621690
97 + 33621593 = 33621690
131 + 33621559 = 33621690
149 + 33621541 = 33621690

Showing the first eight; more decompositions exist.
