Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89388, here are decompositions:

7 + 89381 = 89388
17 + 89371 = 89388
59 + 89329 = 89388
71 + 89317 = 89388
127 + 89261 = 89388
151 + 89237 = 89388
157 + 89231 = 89388
179 + 89209 = 89388

Showing the first eight; more decompositions exist.
