Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 33587678, here are decompositions:

31 + 33587647 = 33587678
97 + 33587581 = 33587678
127 + 33587551 = 33587678
199 + 33587479 = 33587678
277 + 33587401 = 33587678
307 + 33587371 = 33587678
331 + 33587347 = 33587678
367 + 33587311 = 33587678

Showing the first eight; more decompositions exist.
