Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 1020918, here are decompositions:

5 + 1020913 = 1020918
11 + 1020907 = 1020918
37 + 1020881 = 1020918
71 + 1020847 = 1020918
79 + 1020839 = 1020918
97 + 1020821 = 1020918
139 + 1020779 = 1020918
167 + 1020751 = 1020918

Showing the first eight; more decompositions exist.
