Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33518818, here are decompositions:

5 + 33518813 = 33518818
149 + 33518669 = 33518818
167 + 33518651 = 33518818
197 + 33518621 = 33518818
227 + 33518591 = 33518818
401 + 33518417 = 33518818
467 + 33518351 = 33518818
491 + 33518327 = 33518818

Showing the first eight; more decompositions exist.
