Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1027278, here are decompositions:

17 + 1027261 = 1027278
37 + 1027241 = 1027278
67 + 1027211 = 1027278
71 + 1027207 = 1027278
79 + 1027199 = 1027278
89 + 1027189 = 1027278
97 + 1027181 = 1027278
139 + 1027139 = 1027278

Showing the first eight; more decompositions exist.
