Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33606478, here are decompositions:

71 + 33606407 = 33606478
107 + 33606371 = 33606478
179 + 33606299 = 33606478
197 + 33606281 = 33606478
251 + 33606227 = 33606478
461 + 33606017 = 33606478
467 + 33606011 = 33606478
509 + 33605969 = 33606478

Showing the first eight; more decompositions exist.
