Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020138, here are decompositions:

29 + 1020109 = 1020138
37 + 1020101 = 1020138
59 + 1020079 = 1020138
61 + 1020077 = 1020138
79 + 1020059 = 1020138
89 + 1020049 = 1020138
101 + 1020037 = 1020138
127 + 1020011 = 1020138

Showing the first eight; more decompositions exist.
