Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726478, here are decompositions:

11 + 8726467 = 8726478
17 + 8726461 = 8726478
29 + 8726449 = 8726478
31 + 8726447 = 8726478
97 + 8726381 = 8726478
127 + 8726351 = 8726478
149 + 8726329 = 8726478
239 + 8726239 = 8726478

Showing the first eight; more decompositions exist.
