Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33617388, here are decompositions:

5 + 33617383 = 33617388
67 + 33617321 = 33617388
97 + 33617291 = 33617388
127 + 33617261 = 33617388
149 + 33617239 = 33617388
229 + 33617159 = 33617388
317 + 33617071 = 33617388
359 + 33617029 = 33617388

Showing the first eight; more decompositions exist.
