Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 6138, here are decompositions:

5 + 6133 = 6138
7 + 6131 = 6138
17 + 6121 = 6138
37 + 6101 = 6138
47 + 6091 = 6138
59 + 6079 = 6138
71 + 6067 = 6138
101 + 6037 = 6138

Showing the first eight; more decompositions exist.
