Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1013886, here are decompositions:

7 + 1013879 = 1013886
43 + 1013843 = 1013886
47 + 1013839 = 1013886
53 + 1013833 = 1013886
59 + 1013827 = 1013886
67 + 1013819 = 1013886
73 + 1013813 = 1013886
113 + 1013773 = 1013886

Showing the first eight; more decompositions exist.
