Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015266, here are decompositions:

59 + 1015207 = 1015266
67 + 1015199 = 1015266
103 + 1015163 = 1015266
107 + 1015159 = 1015266
127 + 1015139 = 1015266
139 + 1015127 = 1015266
173 + 1015093 = 1015266
193 + 1015073 = 1015266

Showing the first eight; more decompositions exist.
