Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507968, here are decompositions:

31 + 33507937 = 33507968
61 + 33507907 = 33507968
79 + 33507889 = 33507968
337 + 33507631 = 33507968
367 + 33507601 = 33507968
661 + 33507307 = 33507968
709 + 33507259 = 33507968
757 + 33507211 = 33507968

Showing the first eight; more decompositions exist.
