Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726378, here are decompositions:

19 + 8726359 = 8726378
139 + 8726239 = 8726378
151 + 8726227 = 8726378
181 + 8726197 = 8726378
277 + 8726101 = 8726378
379 + 8725999 = 8726378
547 + 8725831 = 8726378
709 + 8725669 = 8726378

Showing the first eight; more decompositions exist.
