Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33489578, here are decompositions:

19 + 33489559 = 33489578
229 + 33489349 = 33489578
337 + 33489241 = 33489578
439 + 33489139 = 33489578
601 + 33488977 = 33489578
631 + 33488947 = 33489578
709 + 33488869 = 33489578
1009 + 33488569 = 33489578

Showing the first eight; more decompositions exist.
