Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1021182, here are decompositions:

23 + 1021159 = 1021182
53 + 1021129 = 1021182
59 + 1021123 = 1021182
89 + 1021093 = 1021182
101 + 1021081 = 1021182
109 + 1021073 = 1021182
139 + 1021043 = 1021182
163 + 1021019 = 1021182

Showing the first eight; more decompositions exist.
