Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507878, here are decompositions:

97 + 33507781 = 33507878
127 + 33507751 = 33507878
199 + 33507679 = 33507878
277 + 33507601 = 33507878
337 + 33507541 = 33507878
499 + 33507379 = 33507878
571 + 33507307 = 33507878
619 + 33507259 = 33507878

Showing the first eight; more decompositions exist.
