Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 68138, here are decompositions:

67 + 68071 = 68138
79 + 68059 = 68138
97 + 68041 = 68138
151 + 67987 = 68138
181 + 67957 = 68138
199 + 67939 = 68138
211 + 67927 = 68138
271 + 67867 = 68138

Showing the first eight; more decompositions exist.
