Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015210, here are decompositions:

3 + 1015207 = 1015210
11 + 1015199 = 1015210
47 + 1015163 = 1015210
71 + 1015139 = 1015210
83 + 1015127 = 1015210
113 + 1015097 = 1015210
137 + 1015073 = 1015210
149 + 1015061 = 1015210

Showing the first eight; more decompositions exist.
