Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507720, here are decompositions:

31 + 33507689 = 33507720
41 + 33507679 = 33507720
73 + 33507647 = 33507720
79 + 33507641 = 33507720
89 + 33507631 = 33507720
97 + 33507623 = 33507720
109 + 33507611 = 33507720
157 + 33507563 = 33507720

Showing the first eight; more decompositions exist.
