Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8742468, here are decompositions:

5 + 8742463 = 8742468
19 + 8742449 = 8742468
47 + 8742421 = 8742468
67 + 8742401 = 8742468
89 + 8742379 = 8742468
101 + 8742367 = 8742468
109 + 8742359 = 8742468
151 + 8742317 = 8742468

Showing the first eight; more decompositions exist.
