Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020558, here are decompositions:

17 + 1020541 = 1020558
29 + 1020529 = 1020558
41 + 1020517 = 1020558
67 + 1020491 = 1020558
101 + 1020457 = 1020558
107 + 1020451 = 1020558
127 + 1020431 = 1020558
139 + 1020419 = 1020558

Showing the first eight; more decompositions exist.
