Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1028862, here are decompositions:

19 + 1028843 = 1028862
53 + 1028809 = 1028862
59 + 1028803 = 1028862
89 + 1028773 = 1028862
101 + 1028761 = 1028862
113 + 1028749 = 1028862
179 + 1028683 = 1028862
181 + 1028681 = 1028862

Showing the first eight; more decompositions exist.
