Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002850, here are decompositions:

29 + 1002821 = 1002850
41 + 1002809 = 1002850
53 + 1002797 = 1002850
83 + 1002767 = 1002850
131 + 1002719 = 1002850
137 + 1002713 = 1002850
197 + 1002653 = 1002850
227 + 1002623 = 1002850

Showing the first eight; more decompositions exist.
