Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33621140, here are decompositions:

31 + 33621109 = 33621140
73 + 33621067 = 33621140
103 + 33621037 = 33621140
109 + 33621031 = 33621140
181 + 33620959 = 33621140
211 + 33620929 = 33621140
229 + 33620911 = 33621140
283 + 33620857 = 33621140

Showing the first eight; more decompositions exist.
