Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578738, here are decompositions:

31 + 33578707 = 33578738
79 + 33578659 = 33578738
97 + 33578641 = 33578738
139 + 33578599 = 33578738
181 + 33578557 = 33578738
229 + 33578509 = 33578738
241 + 33578497 = 33578738
439 + 33578299 = 33578738

Showing the first eight; more decompositions exist.
