Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726408, here are decompositions:

7 + 8726401 = 8726408
79 + 8726329 = 8726408
151 + 8726257 = 8726408
181 + 8726227 = 8726408
199 + 8726209 = 8726408
211 + 8726197 = 8726408
307 + 8726101 = 8726408
409 + 8725999 = 8726408

Showing the first eight; more decompositions exist.
