Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002856, here are decompositions:

3 + 1002853 = 1002856
5 + 1002851 = 1002856
47 + 1002809 = 1002856
59 + 1002797 = 1002856
83 + 1002773 = 1002856
89 + 1002767 = 1002856
137 + 1002719 = 1002856
233 + 1002623 = 1002856

Showing the first eight; more decompositions exist.
