Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618372, here are decompositions:

13 + 33618359 = 33618372
41 + 33618331 = 33618372
43 + 33618329 = 33618372
59 + 33618313 = 33618372
83 + 33618289 = 33618372
163 + 33618209 = 33618372
173 + 33618199 = 33618372
181 + 33618191 = 33618372

Showing the first eight; more decompositions exist.
