Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047138, here are decompositions:

5 + 1047133 = 1047138
7 + 1047131 = 1047138
11 + 1047127 = 1047138
19 + 1047119 = 1047138
31 + 1047107 = 1047138
41 + 1047097 = 1047138
61 + 1047077 = 1047138
97 + 1047041 = 1047138

Showing the first eight; more decompositions exist.
