Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33604640, here are decompositions:

31 + 33604609 = 33604640
67 + 33604573 = 33604640
73 + 33604567 = 33604640
79 + 33604561 = 33604640
103 + 33604537 = 33604640
193 + 33604447 = 33604640
211 + 33604429 = 33604640
229 + 33604411 = 33604640

Showing the first eight; more decompositions exist.
