Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537818, here are decompositions:

109 + 33537709 = 33537818
229 + 33537589 = 33537818
277 + 33537541 = 33537818
409 + 33537409 = 33537818
421 + 33537397 = 33537818
619 + 33537199 = 33537818
631 + 33537187 = 33537818
757 + 33537061 = 33537818

Showing the first eight; more decompositions exist.
