Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89000, here are decompositions:

3 + 88997 = 89000
7 + 88993 = 89000
31 + 88969 = 89000
97 + 88903 = 89000
103 + 88897 = 89000
127 + 88873 = 89000
139 + 88861 = 89000
157 + 88843 = 89000

Showing the first eight; more decompositions exist.
