Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 88138, here are decompositions:

59 + 88079 = 88138
101 + 88037 = 88138
131 + 88007 = 88138
137 + 88001 = 88138
179 + 87959 = 88138
227 + 87911 = 88138
251 + 87887 = 88138
257 + 87881 = 88138

Showing the first eight; more decompositions exist.
