Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021048, here are decompositions:

5 + 1021043 = 1021048
29 + 1021019 = 1021048
47 + 1021001 = 1021048
59 + 1020989 = 1021048
71 + 1020977 = 1021048
89 + 1020959 = 1021048
167 + 1020881 = 1021048
227 + 1020821 = 1021048

Showing the first eight; more decompositions exist.
