Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 99988, here are decompositions:

17 + 99971 = 99988
59 + 99929 = 99988
107 + 99881 = 99988
149 + 99839 = 99988
179 + 99809 = 99988
227 + 99761 = 99988
269 + 99719 = 99988
281 + 99707 = 99988

Showing the first eight; more decompositions exist.
