Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726418, here are decompositions:

17 + 8726401 = 8726418
37 + 8726381 = 8726418
59 + 8726359 = 8726418
61 + 8726357 = 8726418
67 + 8726351 = 8726418
89 + 8726329 = 8726418
179 + 8726239 = 8726418
191 + 8726227 = 8726418

Showing the first eight; more decompositions exist.
