Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018686, here are decompositions:

7 + 1018679 = 1018686
13 + 1018673 = 1018686
17 + 1018669 = 1018686
37 + 1018649 = 1018686
43 + 1018643 = 1018686
73 + 1018613 = 1018686
103 + 1018583 = 1018686
127 + 1018559 = 1018686

Showing the first eight; more decompositions exist.
