Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647684, here are decompositions:

173 + 8647511 = 8647684
293 + 8647391 = 8647684
317 + 8647367 = 8647684
431 + 8647253 = 8647684
491 + 8647193 = 8647684
503 + 8647181 = 8647684
557 + 8647127 = 8647684
593 + 8647091 = 8647684

Showing the first eight; more decompositions exist.
