Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742576, here are decompositions:

5 + 8742571 = 8742576
47 + 8742529 = 8742576
79 + 8742497 = 8742576
83 + 8742493 = 8742576
107 + 8742469 = 8742576
113 + 8742463 = 8742576
127 + 8742449 = 8742576
197 + 8742379 = 8742576

Showing the first eight; more decompositions exist.
