Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705558, here are decompositions:

7 + 8705551 = 8705558
31 + 8705527 = 8705558
67 + 8705491 = 8705558
97 + 8705461 = 8705558
109 + 8705449 = 8705558
139 + 8705419 = 8705558
409 + 8705149 = 8705558
577 + 8704981 = 8705558

Showing the first eight; more decompositions exist.
