Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618220, here are decompositions:

11 + 33618209 = 33618220
29 + 33618191 = 33618220
47 + 33618173 = 33618220
59 + 33618161 = 33618220
71 + 33618149 = 33618220
101 + 33618119 = 33618220
191 + 33618029 = 33618220
257 + 33617963 = 33618220

Showing the first eight; more decompositions exist.
