Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8648778, here are decompositions:

29 + 8648749 = 8648778
31 + 8648747 = 8648778
37 + 8648741 = 8648778
41 + 8648737 = 8648778
101 + 8648677 = 8648778
227 + 8648551 = 8648778
241 + 8648537 = 8648778
277 + 8648501 = 8648778

Showing the first eight; more decompositions exist.
