Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33623680, here are decompositions:

29 + 33623651 = 33623680
47 + 33623633 = 33623680
59 + 33623621 = 33623680
71 + 33623609 = 33623680
173 + 33623507 = 33623680
317 + 33623363 = 33623680
353 + 33623327 = 33623680
449 + 33623231 = 33623680

Showing the first eight; more decompositions exist.
