Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618912, here are decompositions:

23 + 33618889 = 33618912
59 + 33618853 = 33618912
73 + 33618839 = 33618912
139 + 33618773 = 33618912
163 + 33618749 = 33618912
193 + 33618719 = 33618912
241 + 33618671 = 33618912
269 + 33618643 = 33618912

Showing the first eight; more decompositions exist.
