Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33556290, here are decompositions:

59 + 33556231 = 33556290
83 + 33556207 = 33556290
101 + 33556189 = 33556290
107 + 33556183 = 33556290
167 + 33556123 = 33556290
179 + 33556111 = 33556290
197 + 33556093 = 33556290
227 + 33556063 = 33556290

Showing the first eight; more decompositions exist.
