Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989888, here are decompositions:

19 + 989869 = 989888
61 + 989827 = 989888
127 + 989761 = 989888
139 + 989749 = 989888
241 + 989647 = 989888
307 + 989581 = 989888
331 + 989557 = 989888
409 + 989479 = 989888

Showing the first eight; more decompositions exist.
