Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621866, here are decompositions:

7 + 33621859 = 33621866
43 + 33621823 = 33621866
79 + 33621787 = 33621866
139 + 33621727 = 33621866
193 + 33621673 = 33621866
307 + 33621559 = 33621866
457 + 33621409 = 33621866
613 + 33621253 = 33621866

Showing the first eight; more decompositions exist.
