Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618130, here are decompositions:

11 + 33618119 = 33618130
101 + 33618029 = 33618130
131 + 33617999 = 33618130
167 + 33617963 = 33618130
173 + 33617957 = 33618130
197 + 33617933 = 33618130
311 + 33617819 = 33618130
353 + 33617777 = 33618130

Showing the first eight; more decompositions exist.
