Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621784, here are decompositions:

3 + 33621781 = 33621784
23 + 33621761 = 33621784
71 + 33621713 = 33621784
173 + 33621611 = 33621784
191 + 33621593 = 33621784
293 + 33621491 = 33621784
311 + 33621473 = 33621784
347 + 33621437 = 33621784

Showing the first eight; more decompositions exist.
