Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1008862, here are decompositions:

3 + 1008859 = 1008862
5 + 1008857 = 1008862
11 + 1008851 = 1008862
53 + 1008809 = 1008862
83 + 1008779 = 1008862
89 + 1008773 = 1008862
251 + 1008611 = 1008862
359 + 1008503 = 1008862

Showing the first eight; more decompositions exist.
