Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018988, here are decompositions:

7 + 1018981 = 1018988
31 + 1018957 = 1018988
109 + 1018879 = 1018988
181 + 1018807 = 1018988
199 + 1018789 = 1018988
211 + 1018777 = 1018988
277 + 1018711 = 1018988
337 + 1018651 = 1018988

Showing the first eight; more decompositions exist.
