Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33508780, here are decompositions:

47 + 33508733 = 33508780
59 + 33508721 = 33508780
197 + 33508583 = 33508780
281 + 33508499 = 33508780
293 + 33508487 = 33508780
317 + 33508463 = 33508780
419 + 33508361 = 33508780
479 + 33508301 = 33508780

Showing the first eight; more decompositions exist.
