Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742958, here are decompositions:

17 + 8742941 = 8742958
41 + 8742917 = 8742958
71 + 8742887 = 8742958
101 + 8742857 = 8742958
137 + 8742821 = 8742958
179 + 8742779 = 8742958
269 + 8742689 = 8742958
281 + 8742677 = 8742958

Showing the first eight; more decompositions exist.
