Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028786, here are decompositions:

13 + 1028773 = 1028786
37 + 1028749 = 1028786
103 + 1028683 = 1028786
139 + 1028647 = 1028786
229 + 1028557 = 1028786
277 + 1028509 = 1028786
307 + 1028479 = 1028786
313 + 1028473 = 1028786

Showing the first eight; more decompositions exist.
