Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647868, here are decompositions:

67 + 8647801 = 8647868
109 + 8647759 = 8647868
157 + 8647711 = 8647868
211 + 8647657 = 8647868
331 + 8647537 = 8647868
337 + 8647531 = 8647868
367 + 8647501 = 8647868
409 + 8647459 = 8647868

Showing the first eight; more decompositions exist.
