Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33623720, here are decompositions:

19 + 33623701 = 33623720
79 + 33623641 = 33623720
127 + 33623593 = 33623720
157 + 33623563 = 33623720
223 + 33623497 = 33623720
331 + 33623389 = 33623720
349 + 33623371 = 33623720
367 + 33623353 = 33623720

Showing the first eight; more decompositions exist.
