Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 7138, here are decompositions:

11 + 7127 = 7138
17 + 7121 = 7138
29 + 7109 = 7138
59 + 7079 = 7138
137 + 7001 = 7138
167 + 6971 = 7138
179 + 6959 = 7138
191 + 6947 = 7138

Showing the first eight; more decompositions exist.
