Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621878, here are decompositions:

19 + 33621859 = 33621878
97 + 33621781 = 33621878
127 + 33621751 = 33621878
151 + 33621727 = 33621878
229 + 33621649 = 33621878
337 + 33621541 = 33621878
709 + 33621169 = 33621878
769 + 33621109 = 33621878

Showing the first eight; more decompositions exist.
