Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015248, here are decompositions:

41 + 1015207 = 1015248
89 + 1015159 = 1015248
109 + 1015139 = 1015248
151 + 1015097 = 1015248
167 + 1015081 = 1015248
181 + 1015067 = 1015248
191 + 1015057 = 1015248
197 + 1015051 = 1015248

Showing the first eight; more decompositions exist.
