Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33497220, here are decompositions:

13 + 33497207 = 33497220
37 + 33497183 = 33497220
67 + 33497153 = 33497220
79 + 33497141 = 33497220
109 + 33497111 = 33497220
149 + 33497071 = 33497220
151 + 33497069 = 33497220
157 + 33497063 = 33497220

Showing the first eight; more decompositions exist.
