Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507840, here are decompositions:

19 + 33507821 = 33507840
31 + 33507809 = 33507840
43 + 33507797 = 33507840
59 + 33507781 = 33507840
61 + 33507779 = 33507840
89 + 33507751 = 33507840
97 + 33507743 = 33507840
103 + 33507737 = 33507840

Showing the first eight; more decompositions exist.
