Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015212, here are decompositions:

5 + 1015207 = 1015212
13 + 1015199 = 1015212
41 + 1015171 = 1015212
53 + 1015159 = 1015212
73 + 1015139 = 1015212
89 + 1015123 = 1015212
131 + 1015081 = 1015212
139 + 1015073 = 1015212

Showing the first eight; more decompositions exist.
