Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 4138, here are decompositions:

5 + 4133 = 4138
11 + 4127 = 4138
47 + 4091 = 4138
59 + 4079 = 4138
89 + 4049 = 4138
131 + 4007 = 4138
137 + 4001 = 4138
149 + 3989 = 4138

Showing the first eight; more decompositions exist.
