Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8705506, here are decompositions:

23 + 8705483 = 8705506
53 + 8705453 = 8705506
107 + 8705399 = 8705506
137 + 8705369 = 8705506
269 + 8705237 = 8705506
347 + 8705159 = 8705506
419 + 8705087 = 8705506
449 + 8705057 = 8705506

Showing the first eight; more decompositions exist.
