Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021126, here are decompositions:

3 + 1021123 = 1021126
53 + 1021073 = 1021126
59 + 1021067 = 1021126
83 + 1021043 = 1021126
107 + 1021019 = 1021126
137 + 1020989 = 1021126
149 + 1020977 = 1021126
167 + 1020959 = 1021126

Showing the first eight; more decompositions exist.
