Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649308, here are decompositions:

67 + 8649241 = 8649308
97 + 8649211 = 8649308
229 + 8649079 = 8649308
307 + 8649001 = 8649308
379 + 8648929 = 8649308
571 + 8648737 = 8649308
607 + 8648701 = 8649308
631 + 8648677 = 8649308

Showing the first eight; more decompositions exist.
