Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621788, here are decompositions:

7 + 33621781 = 33621788
37 + 33621751 = 33621788
61 + 33621727 = 33621788
97 + 33621691 = 33621788
127 + 33621661 = 33621788
139 + 33621649 = 33621788
229 + 33621559 = 33621788
379 + 33621409 = 33621788

Showing the first eight; more decompositions exist.
