Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621518, here are decompositions:

109 + 33621409 = 33621518
157 + 33621361 = 33621518
349 + 33621169 = 33621518
409 + 33621109 = 33621518
487 + 33621031 = 33621518
607 + 33620911 = 33621518
661 + 33620857 = 33621518
709 + 33620809 = 33621518

Showing the first eight; more decompositions exist.
