Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33515838, here are decompositions:

7 + 33515831 = 33515838
67 + 33515771 = 33515838
79 + 33515759 = 33515838
127 + 33515711 = 33515838
131 + 33515707 = 33515838
137 + 33515701 = 33515838
229 + 33515609 = 33515838
269 + 33515569 = 33515838

Showing the first eight; more decompositions exist.
