Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8726438, here are decompositions:

37 + 8726401 = 8726438
79 + 8726359 = 8726438
109 + 8726329 = 8726438
181 + 8726257 = 8726438
199 + 8726239 = 8726438
211 + 8726227 = 8726438
229 + 8726209 = 8726438
241 + 8726197 = 8726438

Showing the first eight; more decompositions exist.
