Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1002918, here are decompositions:

5 + 1002913 = 1002918
19 + 1002899 = 1002918
31 + 1002887 = 1002918
47 + 1002871 = 1002918
61 + 1002857 = 1002918
67 + 1002851 = 1002918
97 + 1002821 = 1002918
101 + 1002817 = 1002918

Showing the first eight; more decompositions exist.
