Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705478, here are decompositions:

11 + 8705467 = 8705478
17 + 8705461 = 8705478
29 + 8705449 = 8705478
37 + 8705441 = 8705478
59 + 8705419 = 8705478
79 + 8705399 = 8705478
109 + 8705369 = 8705478
127 + 8705351 = 8705478

Showing the first eight; more decompositions exist.
