Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621958, here are decompositions:

47 + 33621911 = 33621958
101 + 33621857 = 33621958
197 + 33621761 = 33621958
347 + 33621611 = 33621958
467 + 33621491 = 33621958
521 + 33621437 = 33621958
569 + 33621389 = 33621958
647 + 33621311 = 33621958

Showing the first eight; more decompositions exist.
