Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 988288, here are decompositions:

17 + 988271 = 988288
71 + 988217 = 988288
89 + 988199 = 988288
131 + 988157 = 988288
179 + 988109 = 988288
227 + 988061 = 988288
281 + 988007 = 988288
317 + 987971 = 988288

Showing the first eight; more decompositions exist.
