Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507780, here are decompositions:

17 + 33507763 = 33507780
29 + 33507751 = 33507780
37 + 33507743 = 33507780
43 + 33507737 = 33507780
101 + 33507679 = 33507780
109 + 33507671 = 33507780
139 + 33507641 = 33507780
149 + 33507631 = 33507780

Showing the first eight; more decompositions exist.
