Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742522, here are decompositions:

11 + 8742511 = 8742522
23 + 8742499 = 8742522
29 + 8742493 = 8742522
53 + 8742469 = 8742522
59 + 8742463 = 8742522
73 + 8742449 = 8742522
101 + 8742421 = 8742522
163 + 8742359 = 8742522

Showing the first eight; more decompositions exist.
