Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33488768, here are decompositions:

199 + 33488569 = 33488768
211 + 33488557 = 33488768
277 + 33488491 = 33488768
307 + 33488461 = 33488768
457 + 33488311 = 33488768
487 + 33488281 = 33488768
601 + 33488167 = 33488768
631 + 33488137 = 33488768

Showing the first eight; more decompositions exist.
