Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33507756, here are decompositions:

5 + 33507751 = 33507756
13 + 33507743 = 33507756
19 + 33507737 = 33507756
67 + 33507689 = 33507756
109 + 33507647 = 33507756
157 + 33507599 = 33507756
179 + 33507577 = 33507756
193 + 33507563 = 33507756

Showing the first eight; more decompositions exist.
