Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 103138, here are decompositions:

47 + 103091 = 103138
59 + 103079 = 103138
71 + 103067 = 103138
89 + 103049 = 103138
131 + 103007 = 103138
137 + 103001 = 103138
227 + 102911 = 103138
257 + 102881 = 103138

Showing the first eight; more decompositions exist.
