Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718558, here are decompositions:

19 + 8718539 = 8718558
67 + 8718491 = 8718558
71 + 8718487 = 8718558
89 + 8718469 = 8718558
97 + 8718461 = 8718558
127 + 8718431 = 8718558
131 + 8718427 = 8718558
139 + 8718419 = 8718558

Showing the first eight; more decompositions exist.
