Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521648, here are decompositions:

19 + 33521629 = 33521648
109 + 33521539 = 33521648
211 + 33521437 = 33521648
661 + 33520987 = 33521648
709 + 33520939 = 33521648
757 + 33520891 = 33521648
967 + 33520681 = 33521648
1087 + 33520561 = 33521648

Showing the first eight; more decompositions exist.
