Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33523668, here are decompositions:

5 + 33523663 = 33523668
67 + 33523601 = 33523668
89 + 33523579 = 33523668
149 + 33523519 = 33523668
257 + 33523411 = 33523668
397 + 33523271 = 33523668
421 + 33523247 = 33523668
439 + 33523229 = 33523668

Showing the first eight; more decompositions exist.
