Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027218, here are decompositions:

7 + 1027211 = 1027218
11 + 1027207 = 1027218
19 + 1027199 = 1027218
29 + 1027189 = 1027218
37 + 1027181 = 1027218
79 + 1027139 = 1027218
89 + 1027129 = 1027218
151 + 1027067 = 1027218

Showing the first eight; more decompositions exist.
