Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008138, here are decompositions:

7 + 1008131 = 1008138
37 + 1008101 = 1008138
97 + 1008041 = 1008138
101 + 1008037 = 1008138
107 + 1008031 = 1008138
137 + 1008001 = 1008138
167 + 1007971 = 1008138
179 + 1007959 = 1008138

Showing the first eight; more decompositions exist.
