Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015206, here are decompositions:

7 + 1015199 = 1015206
43 + 1015163 = 1015206
47 + 1015159 = 1015206
67 + 1015139 = 1015206
79 + 1015127 = 1015206
83 + 1015123 = 1015206
109 + 1015097 = 1015206
113 + 1015093 = 1015206

Showing the first eight; more decompositions exist.
