Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621438, here are decompositions:

29 + 33621409 = 33621438
31 + 33621407 = 33621438
41 + 33621397 = 33621438
127 + 33621311 = 33621438
139 + 33621299 = 33621438
269 + 33621169 = 33621438
401 + 33621037 = 33621438
439 + 33620999 = 33621438

Showing the first eight; more decompositions exist.
