Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020618, here are decompositions:

19 + 1020599 = 1020618
29 + 1020589 = 1020618
61 + 1020557 = 1020618
89 + 1020529 = 1020618
101 + 1020517 = 1020618
127 + 1020491 = 1020618
167 + 1020451 = 1020618
199 + 1020419 = 1020618

Showing the first eight; more decompositions exist.
