Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33503780, here are decompositions:

7 + 33503773 = 33503780
31 + 33503749 = 33503780
103 + 33503677 = 33503780
139 + 33503641 = 33503780
151 + 33503629 = 33503780
181 + 33503599 = 33503780
199 + 33503581 = 33503780
223 + 33503557 = 33503780

Showing the first eight; more decompositions exist.
