Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618378, here are decompositions:

19 + 33618359 = 33618378
47 + 33618331 = 33618378
61 + 33618317 = 33618378
71 + 33618307 = 33618378
89 + 33618289 = 33618378
127 + 33618251 = 33618378
179 + 33618199 = 33618378
229 + 33618149 = 33618378

Showing the first eight; more decompositions exist.
