Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618580, here are decompositions:

3 + 33618577 = 33618580
89 + 33618491 = 33618580
137 + 33618443 = 33618580
167 + 33618413 = 33618580
251 + 33618329 = 33618580
257 + 33618323 = 33618580
263 + 33618317 = 33618580
389 + 33618191 = 33618580

Showing the first eight; more decompositions exist.
