Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33503688, here are decompositions:

11 + 33503677 = 33503688
47 + 33503641 = 33503688
59 + 33503629 = 33503688
61 + 33503627 = 33503688
89 + 33503599 = 33503688
107 + 33503581 = 33503688
131 + 33503557 = 33503688
149 + 33503539 = 33503688

Showing the first eight; more decompositions exist.
