Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8688558, here are decompositions:

5 + 8688553 = 8688558
7 + 8688551 = 8688558
31 + 8688527 = 8688558
37 + 8688521 = 8688558
61 + 8688497 = 8688558
89 + 8688469 = 8688558
149 + 8688409 = 8688558
271 + 8688287 = 8688558

Showing the first eight; more decompositions exist.
