Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521690, here are decompositions:

43 + 33521647 = 33521690
61 + 33521629 = 33521690
67 + 33521623 = 33521690
151 + 33521539 = 33521690
229 + 33521461 = 33521690
607 + 33521083 = 33521690
751 + 33520939 = 33521690
877 + 33520813 = 33521690

Showing the first eight; more decompositions exist.
