Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621458, here are decompositions:

61 + 33621397 = 33621458
97 + 33621361 = 33621458
349 + 33621109 = 33621458
421 + 33621037 = 33621458
499 + 33620959 = 33621458
547 + 33620911 = 33621458
601 + 33620857 = 33621458
691 + 33620767 = 33621458

Showing the first eight; more decompositions exist.
