Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647880, here are decompositions:

61 + 8647819 = 8647880
79 + 8647801 = 8647880
97 + 8647783 = 8647880
127 + 8647753 = 8647880
181 + 8647699 = 8647880
223 + 8647657 = 8647880
313 + 8647567 = 8647880
349 + 8647531 = 8647880

Showing the first eight; more decompositions exist.
