Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8715458, here are decompositions:

7 + 8715451 = 8715458
97 + 8715361 = 8715458
109 + 8715349 = 8715458
277 + 8715181 = 8715458
307 + 8715151 = 8715458
379 + 8715079 = 8715458
439 + 8715019 = 8715458
601 + 8714857 = 8715458

Showing the first eight; more decompositions exist.
