Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 10138, here are decompositions:

5 + 10133 = 10138
47 + 10091 = 10138
59 + 10079 = 10138
71 + 10067 = 10138
101 + 10037 = 10138
131 + 10007 = 10138
197 + 9941 = 10138
251 + 9887 = 10138

Showing the first eight; more decompositions exist.
