Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33578618, here are decompositions:

19 + 33578599 = 33578618
61 + 33578557 = 33578618
109 + 33578509 = 33578618
181 + 33578437 = 33578618
331 + 33578287 = 33578618
349 + 33578269 = 33578618
421 + 33578197 = 33578618
487 + 33578131 = 33578618

Showing the first eight; more decompositions exist.
