Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647326, here are decompositions:

53 + 8647273 = 8647326
73 + 8647253 = 8647326
97 + 8647229 = 8647326
197 + 8647129 = 8647326
199 + 8647127 = 8647326
263 + 8647063 = 8647326
283 + 8647043 = 8647326
379 + 8646947 = 8647326

Showing the first eight; more decompositions exist.
