Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33485840, here are decompositions:

7 + 33485833 = 33485840
19 + 33485821 = 33485840
61 + 33485779 = 33485840
67 + 33485773 = 33485840
109 + 33485731 = 33485840
127 + 33485713 = 33485840
139 + 33485701 = 33485840
151 + 33485689 = 33485840

Showing the first eight; more decompositions exist.
