Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618636, here are decompositions:

59 + 33618577 = 33618636
193 + 33618443 = 33618636
197 + 33618439 = 33618636
223 + 33618413 = 33618636
257 + 33618379 = 33618636
277 + 33618359 = 33618636
307 + 33618329 = 33618636
313 + 33618323 = 33618636

Showing the first eight; more decompositions exist.
