Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647502, here are decompositions:

43 + 8647459 = 8647502
109 + 8647393 = 8647502
229 + 8647273 = 8647502
271 + 8647231 = 8647502
373 + 8647129 = 8647502
379 + 8647123 = 8647502
439 + 8647063 = 8647502
541 + 8646961 = 8647502

Showing the first eight; more decompositions exist.
