Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647832, here are decompositions:

13 + 8647819 = 8647832
31 + 8647801 = 8647832
73 + 8647759 = 8647832
79 + 8647753 = 8647832
331 + 8647501 = 8647832
373 + 8647459 = 8647832
421 + 8647411 = 8647832
439 + 8647393 = 8647832

Showing the first eight; more decompositions exist.
