Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33623420, here are decompositions:

31 + 33623389 = 33623420
67 + 33623353 = 33623420
79 + 33623341 = 33623420
97 + 33623323 = 33623420
283 + 33623137 = 33623420
331 + 33623089 = 33623420
349 + 33623071 = 33623420
487 + 33622933 = 33623420

Showing the first eight; more decompositions exist.
