Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1047142, here are decompositions:

3 + 1047139 = 1047142
11 + 1047131 = 1047142
23 + 1047119 = 1047142
53 + 1047089 = 1047142
101 + 1047041 = 1047142
149 + 1046993 = 1047142
191 + 1046951 = 1047142
293 + 1046849 = 1047142

Showing the first eight; more decompositions exist.
