Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988888, here are decompositions:

11 + 988877 = 988888
29 + 988859 = 988888
59 + 988829 = 988888
227 + 988661 = 988888
239 + 988649 = 988888
281 + 988607 = 988888
311 + 988577 = 988888
317 + 988571 = 988888

Showing the first eight; more decompositions exist.
