Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1022938, here are decompositions:

5 + 1022933 = 1022938
47 + 1022891 = 1022938
89 + 1022849 = 1022938
101 + 1022837 = 1022938
347 + 1022591 = 1022938
419 + 1022519 = 1022938
431 + 1022507 = 1022938
509 + 1022429 = 1022938

Showing the first eight; more decompositions exist.
