Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33487656, here are decompositions:

5 + 33487651 = 33487656
17 + 33487639 = 33487656
113 + 33487543 = 33487656
149 + 33487507 = 33487656
179 + 33487477 = 33487656
233 + 33487423 = 33487656
239 + 33487417 = 33487656
263 + 33487393 = 33487656

Showing the first eight; more decompositions exist.
