Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508420, here are decompositions:

3 + 33508417 = 33508420
59 + 33508361 = 33508420
131 + 33508289 = 33508420
293 + 33508127 = 33508420
311 + 33508109 = 33508420
317 + 33508103 = 33508420
353 + 33508067 = 33508420
401 + 33508019 = 33508420

Showing the first eight; more decompositions exist.
