Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002858, here are decompositions:

5 + 1002853 = 1002858
7 + 1002851 = 1002858
37 + 1002821 = 1002858
41 + 1002817 = 1002858
61 + 1002797 = 1002858
71 + 1002787 = 1002858
89 + 1002769 = 1002858
107 + 1002751 = 1002858

Showing the first eight; more decompositions exist.
