Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515660, here are decompositions:

43 + 33515617 = 33515660
67 + 33515593 = 33515660
151 + 33515509 = 33515660
223 + 33515437 = 33515660
229 + 33515431 = 33515660
337 + 33515323 = 33515660
457 + 33515203 = 33515660
601 + 33515059 = 33515660

Showing the first eight; more decompositions exist.
