Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742516, here are decompositions:

5 + 8742511 = 8742516
17 + 8742499 = 8742516
19 + 8742497 = 8742516
23 + 8742493 = 8742516
47 + 8742469 = 8742516
53 + 8742463 = 8742516
67 + 8742449 = 8742516
137 + 8742379 = 8742516

Showing the first eight; more decompositions exist.
