Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578960, here are decompositions:

43 + 33578917 = 33578960
73 + 33578887 = 33578960
97 + 33578863 = 33578960
193 + 33578767 = 33578960
199 + 33578761 = 33578960
211 + 33578749 = 33578960
277 + 33578683 = 33578960
463 + 33578497 = 33578960

Showing the first eight; more decompositions exist.
