Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618720, here are decompositions:

227 + 33618493 = 33618720
229 + 33618491 = 33618720
269 + 33618451 = 33618720
277 + 33618443 = 33618720
281 + 33618439 = 33618720
307 + 33618413 = 33618720
389 + 33618331 = 33618720
397 + 33618323 = 33618720

Showing the first eight; more decompositions exist.
