Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8647772, here are decompositions:

13 + 8647759 = 8647772
19 + 8647753 = 8647772
61 + 8647711 = 8647772
73 + 8647699 = 8647772
193 + 8647579 = 8647772
241 + 8647531 = 8647772
271 + 8647501 = 8647772
313 + 8647459 = 8647772

Showing the first eight; more decompositions exist.
