Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647498, here are decompositions:

29 + 8647469 = 8647498
89 + 8647409 = 8647498
107 + 8647391 = 8647498
131 + 8647367 = 8647498
149 + 8647349 = 8647498
269 + 8647229 = 8647498
317 + 8647181 = 8647498
359 + 8647139 = 8647498

Showing the first eight; more decompositions exist.
