Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1019278, here are decompositions:

5 + 1019273 = 1019278
11 + 1019267 = 1019278
17 + 1019261 = 1019278
41 + 1019237 = 1019278
101 + 1019177 = 1019278
149 + 1019129 = 1019278
311 + 1018967 = 1019278
347 + 1018931 = 1019278

Showing the first eight; more decompositions exist.
