Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 89138, here are decompositions:

19 + 89119 = 89138
31 + 89107 = 89138
37 + 89101 = 89138
67 + 89071 = 89138
97 + 89041 = 89138
241 + 88897 = 89138
271 + 88867 = 89138
277 + 88861 = 89138

Showing the first eight; more decompositions exist.
