Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621800, here are decompositions:

13 + 33621787 = 33621800
19 + 33621781 = 33621800
73 + 33621727 = 33621800
109 + 33621691 = 33621800
127 + 33621673 = 33621800
139 + 33621661 = 33621800
151 + 33621649 = 33621800
241 + 33621559 = 33621800

Showing the first eight; more decompositions exist.
