Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33537678, here are decompositions:

79 + 33537599 = 33537678
89 + 33537589 = 33537678
107 + 33537571 = 33537678
127 + 33537551 = 33537678
137 + 33537541 = 33537678
149 + 33537529 = 33537678
241 + 33537437 = 33537678
269 + 33537409 = 33537678

Showing the first eight; more decompositions exist.
