Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002906, here are decompositions:

7 + 1002899 = 1002906
13 + 1002893 = 1002906
19 + 1002887 = 1002906
43 + 1002863 = 1002906
53 + 1002853 = 1002906
89 + 1002817 = 1002906
97 + 1002809 = 1002906
109 + 1002797 = 1002906

Showing the first eight; more decompositions exist.
