Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015148, here are decompositions:

67 + 1015081 = 1015148
97 + 1015051 = 1015148
109 + 1015039 = 1015148
139 + 1015009 = 1015148
241 + 1014907 = 1015148
271 + 1014877 = 1015148
331 + 1014817 = 1015148
499 + 1014649 = 1015148

Showing the first eight; more decompositions exist.
