Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621644, here are decompositions:

103 + 33621541 = 33621644
283 + 33621361 = 33621644
577 + 33621067 = 33621644
607 + 33621037 = 33621644
613 + 33621031 = 33621644
733 + 33620911 = 33621644
787 + 33620857 = 33621644
877 + 33620767 = 33621644

Showing the first eight; more decompositions exist.
