Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020078, here are decompositions:

19 + 1020059 = 1020078
29 + 1020049 = 1020078
41 + 1020037 = 1020078
67 + 1020011 = 1020078
71 + 1020007 = 1020078
107 + 1019971 = 1020078
151 + 1019927 = 1020078
179 + 1019899 = 1020078

Showing the first eight; more decompositions exist.
