Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988388, here are decompositions:

31 + 988357 = 988388
67 + 988321 = 988388
109 + 988279 = 988388
151 + 988237 = 988388
157 + 988231 = 988388
241 + 988147 = 988388
277 + 988111 = 988388
337 + 988051 = 988388

Showing the first eight; more decompositions exist.
