Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621974, here are decompositions:

73 + 33621901 = 33621974
151 + 33621823 = 33621974
193 + 33621781 = 33621974
223 + 33621751 = 33621974
283 + 33621691 = 33621974
313 + 33621661 = 33621974
433 + 33621541 = 33621974
577 + 33621397 = 33621974

Showing the first eight; more decompositions exist.
