Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587638, here are decompositions:

5 + 33587633 = 33587638
89 + 33587549 = 33587638
101 + 33587537 = 33587638
131 + 33587507 = 33587638
167 + 33587471 = 33587638
281 + 33587357 = 33587638
317 + 33587321 = 33587638
401 + 33587237 = 33587638

Showing the first eight; more decompositions exist.
