Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33618642, here are decompositions:

149 + 33618493 = 33618642
151 + 33618491 = 33618642
191 + 33618451 = 33618642
199 + 33618443 = 33618642
229 + 33618413 = 33618642
263 + 33618379 = 33618642
283 + 33618359 = 33618642
311 + 33618331 = 33618642

Showing the first eight; more decompositions exist.
