Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742970, here are decompositions:

29 + 8742941 = 8742970
53 + 8742917 = 8742970
83 + 8742887 = 8742970
113 + 8742857 = 8742970
149 + 8742821 = 8742970
191 + 8742779 = 8742970
281 + 8742689 = 8742970
293 + 8742677 = 8742970

Showing the first eight; more decompositions exist.
