Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1015078, here are decompositions:

5 + 1015073 = 1015078
11 + 1015067 = 1015078
17 + 1015061 = 1015078
89 + 1014989 = 1015078
137 + 1014941 = 1015078
191 + 1014887 = 1015078
257 + 1014821 = 1015078
347 + 1014731 = 1015078

Showing the first eight; more decompositions exist.
