Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621782, here are decompositions:

31 + 33621751 = 33621782
109 + 33621673 = 33621782
223 + 33621559 = 33621782
241 + 33621541 = 33621782
373 + 33621409 = 33621782
421 + 33621361 = 33621782
499 + 33621283 = 33621782
613 + 33621169 = 33621782

Showing the first eight; more decompositions exist.
