Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 5138, here are decompositions:

19 + 5119 = 5138
31 + 5107 = 5138
37 + 5101 = 5138
61 + 5077 = 5138
79 + 5059 = 5138
127 + 5011 = 5138
139 + 4999 = 5138
151 + 4987 = 5138

Showing the first eight; more decompositions exist.
