Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89428, here are decompositions:

11 + 89417 = 89428
29 + 89399 = 89428
41 + 89387 = 89428
47 + 89381 = 89428
167 + 89261 = 89428
191 + 89237 = 89428
197 + 89231 = 89428
239 + 89189 = 89428

Showing the first eight; more decompositions exist.
