Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618904, here are decompositions:

17 + 33618887 = 33618904
47 + 33618857 = 33618904
131 + 33618773 = 33618904
167 + 33618737 = 33618904
233 + 33618671 = 33618904
461 + 33618443 = 33618904
491 + 33618413 = 33618904
587 + 33618317 = 33618904

Showing the first eight; more decompositions exist.
