Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1018278, here are decompositions:

7 + 1018271 = 1018278
31 + 1018247 = 1018278
61 + 1018217 = 1018278
71 + 1018207 = 1018278
101 + 1018177 = 1018278
181 + 1018097 = 1018278
257 + 1018021 = 1018278
271 + 1018007 = 1018278

Showing the first eight; more decompositions exist.
