Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507782, here are decompositions:

3 + 33507779 = 33507782
19 + 33507763 = 33507782
31 + 33507751 = 33507782
103 + 33507679 = 33507782
151 + 33507631 = 33507782
181 + 33507601 = 33507782
241 + 33507541 = 33507782
463 + 33507319 = 33507782

Showing the first eight; more decompositions exist.
