Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33521760, here are decompositions:

7 + 33521753 = 33521760
29 + 33521731 = 33521760
31 + 33521729 = 33521760
47 + 33521713 = 33521760
59 + 33521701 = 33521760
67 + 33521693 = 33521760
71 + 33521689 = 33521760
113 + 33521647 = 33521760

Showing the first eight; more decompositions exist.
