Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015668, here are decompositions:

7 + 1015661 = 1015668
41 + 1015627 = 1015668
67 + 1015601 = 1015668
97 + 1015571 = 1015668
107 + 1015561 = 1015668
109 + 1015559 = 1015668
127 + 1015541 = 1015668
151 + 1015517 = 1015668

Showing the first eight; more decompositions exist.
