Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742510, here are decompositions:

11 + 8742499 = 8742510
13 + 8742497 = 8742510
17 + 8742493 = 8742510
41 + 8742469 = 8742510
47 + 8742463 = 8742510
61 + 8742449 = 8742510
89 + 8742421 = 8742510
109 + 8742401 = 8742510

Showing the first eight; more decompositions exist.
