Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485972, here are decompositions:

31 + 33485941 = 33485972
139 + 33485833 = 33485972
151 + 33485821 = 33485972
181 + 33485791 = 33485972
193 + 33485779 = 33485972
199 + 33485773 = 33485972
241 + 33485731 = 33485972
271 + 33485701 = 33485972

Showing the first eight; more decompositions exist.
