Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988508, here are decompositions:

7 + 988501 = 988508
19 + 988489 = 988508
151 + 988357 = 988508
211 + 988297 = 988508
229 + 988279 = 988508
271 + 988237 = 988508
277 + 988231 = 988508
379 + 988129 = 988508

Showing the first eight; more decompositions exist.
