Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33509978, here are decompositions:

157 + 33509821 = 33509978
331 + 33509647 = 33509978
409 + 33509569 = 33509978
577 + 33509401 = 33509978
709 + 33509269 = 33509978
769 + 33509209 = 33509978
829 + 33509149 = 33509978
907 + 33509071 = 33509978

Showing the first eight; more decompositions exist.
