Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015018, here are decompositions:

29 + 1014989 = 1015018
131 + 1014887 = 1015018
149 + 1014869 = 1015018
197 + 1014821 = 1015018
239 + 1014779 = 1015018
269 + 1014749 = 1015018
401 + 1014617 = 1015018
461 + 1014557 = 1015018

Showing the first eight; more decompositions exist.
