Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578540, here are decompositions:

7 + 33578533 = 33578540
31 + 33578509 = 33578540
43 + 33578497 = 33578540
67 + 33578473 = 33578540
97 + 33578443 = 33578540
103 + 33578437 = 33578540
241 + 33578299 = 33578540
271 + 33578269 = 33578540

Showing the first eight; more decompositions exist.
