Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649248, here are decompositions:

7 + 8649241 = 8649248
37 + 8649211 = 8649248
61 + 8649187 = 8649248
199 + 8649049 = 8649248
367 + 8648881 = 8649248
409 + 8648839 = 8649248
457 + 8648791 = 8649248
499 + 8648749 = 8649248

Showing the first eight; more decompositions exist.
