Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027188, here are decompositions:

7 + 1027181 = 1027188
59 + 1027129 = 1027188
61 + 1027127 = 1027188
137 + 1027051 = 1027188
157 + 1027031 = 1027188
199 + 1026989 = 1027188
241 + 1026947 = 1027188
271 + 1026917 = 1027188

Showing the first eight; more decompositions exist.
