Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 989998, here are decompositions:

17 + 989981 = 989998
47 + 989951 = 989998
59 + 989939 = 989998
89 + 989909 = 989998
167 + 989831 = 989998
311 + 989687 = 989998
419 + 989579 = 989998
491 + 989507 = 989998

Showing the first eight; more decompositions exist.
