Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015666, here are decompositions:

5 + 1015661 = 1015666
107 + 1015559 = 1015666
149 + 1015517 = 1015666
167 + 1015499 = 1015666
233 + 1015433 = 1015666
257 + 1015409 = 1015666
263 + 1015403 = 1015666
317 + 1015349 = 1015666

Showing the first eight; more decompositions exist.
