Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621984, here are decompositions:

61 + 33621923 = 33621984
73 + 33621911 = 33621984
83 + 33621901 = 33621984
103 + 33621881 = 33621984
127 + 33621857 = 33621984
197 + 33621787 = 33621984
223 + 33621761 = 33621984
233 + 33621751 = 33621984

Showing the first eight; more decompositions exist.
