Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647468, here are decompositions:

59 + 8647409 = 8647468
101 + 8647367 = 8647468
191 + 8647277 = 8647468
239 + 8647229 = 8647468
311 + 8647157 = 8647468
461 + 8647007 = 8647468
521 + 8646947 = 8647468
569 + 8646899 = 8647468

Showing the first eight; more decompositions exist.
