Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507810, here are decompositions:

13 + 33507797 = 33507810
29 + 33507781 = 33507810
31 + 33507779 = 33507810
47 + 33507763 = 33507810
59 + 33507751 = 33507810
67 + 33507743 = 33507810
73 + 33507737 = 33507810
131 + 33507679 = 33507810

Showing the first eight; more decompositions exist.
