Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33477220, here are decompositions:

17 + 33477203 = 33477220
59 + 33477161 = 33477220
149 + 33477071 = 33477220
197 + 33477023 = 33477220
239 + 33476981 = 33477220
383 + 33476837 = 33477220
449 + 33476771 = 33477220
503 + 33476717 = 33477220

Showing the first eight; more decompositions exist.
