Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621678, here are decompositions:

5 + 33621673 = 33621678
17 + 33621661 = 33621678
29 + 33621649 = 33621678
67 + 33621611 = 33621678
137 + 33621541 = 33621678
241 + 33621437 = 33621678
269 + 33621409 = 33621678
271 + 33621407 = 33621678

Showing the first eight; more decompositions exist.
