Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742946, here are decompositions:

5 + 8742941 = 8742946
29 + 8742917 = 8742946
59 + 8742887 = 8742946
89 + 8742857 = 8742946
167 + 8742779 = 8742946
257 + 8742689 = 8742946
269 + 8742677 = 8742946
293 + 8742653 = 8742946

Showing the first eight; more decompositions exist.
