Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33503720, here are decompositions:

31 + 33503689 = 33503720
43 + 33503677 = 33503720
79 + 33503641 = 33503720
139 + 33503581 = 33503720
163 + 33503557 = 33503720
181 + 33503539 = 33503720
277 + 33503443 = 33503720
421 + 33503299 = 33503720

Showing the first eight; more decompositions exist.
