Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726624, here are decompositions:

13 + 8726611 = 8726624
37 + 8726587 = 8726624
97 + 8726527 = 8726624
103 + 8726521 = 8726624
157 + 8726467 = 8726624
163 + 8726461 = 8726624
223 + 8726401 = 8726624
241 + 8726383 = 8726624

Showing the first eight; more decompositions exist.
