Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647580, here are decompositions:

13 + 8647567 = 8647580
43 + 8647537 = 8647580
79 + 8647501 = 8647580
163 + 8647417 = 8647580
211 + 8647369 = 8647580
307 + 8647273 = 8647580
349 + 8647231 = 8647580
397 + 8647183 = 8647580

Showing the first eight; more decompositions exist.
