Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726732, here are decompositions:

19 + 8726713 = 8726732
61 + 8726671 = 8726732
163 + 8726569 = 8726732
199 + 8726533 = 8726732
211 + 8726521 = 8726732
271 + 8726461 = 8726732
283 + 8726449 = 8726732
331 + 8726401 = 8726732

Showing the first eight; more decompositions exist.
