Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015740, here are decompositions:

13 + 1015727 = 1015740
17 + 1015723 = 1015740
31 + 1015709 = 1015740
43 + 1015697 = 1015740
79 + 1015661 = 1015740
113 + 1015627 = 1015740
137 + 1015603 = 1015740
139 + 1015601 = 1015740

Showing the first eight; more decompositions exist.
