Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020942, here are decompositions:

11 + 1020931 = 1020942
29 + 1020913 = 1020942
61 + 1020881 = 1020942
89 + 1020853 = 1020942
101 + 1020841 = 1020942
103 + 1020839 = 1020942
163 + 1020779 = 1020942
191 + 1020751 = 1020942

Showing the first eight; more decompositions exist.
