Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33481940, here are decompositions:

31 + 33481909 = 33481940
103 + 33481837 = 33481940
109 + 33481831 = 33481940
139 + 33481801 = 33481940
157 + 33481783 = 33481940
181 + 33481759 = 33481940
211 + 33481729 = 33481940
313 + 33481627 = 33481940

Showing the first eight; more decompositions exist.
