Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621844, here are decompositions:

5 + 33621839 = 33621844
83 + 33621761 = 33621844
131 + 33621713 = 33621844
233 + 33621611 = 33621844
251 + 33621593 = 33621844
353 + 33621491 = 33621844
461 + 33621383 = 33621844
593 + 33621251 = 33621844

Showing the first eight; more decompositions exist.
