Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020538, here are decompositions:

47 + 1020491 = 1020538
107 + 1020431 = 1020538
131 + 1020407 = 1020538
137 + 1020401 = 1020538
149 + 1020389 = 1020538
269 + 1020269 = 1020538
401 + 1020137 = 1020538
461 + 1020077 = 1020538

Showing the first eight; more decompositions exist.
