Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647726, here are decompositions:

29 + 8647697 = 8647726
137 + 8647589 = 8647726
257 + 8647469 = 8647726
317 + 8647409 = 8647726
359 + 8647367 = 8647726
449 + 8647277 = 8647726
569 + 8647157 = 8647726
587 + 8647139 = 8647726

Showing the first eight; more decompositions exist.
