Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621820, here are decompositions:

59 + 33621761 = 33621820
107 + 33621713 = 33621820
191 + 33621629 = 33621820
227 + 33621593 = 33621820
347 + 33621473 = 33621820
383 + 33621437 = 33621820
431 + 33621389 = 33621820
509 + 33621311 = 33621820

Showing the first eight; more decompositions exist.
