Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649848, here are decompositions:

127 + 8649721 = 8649848
157 + 8649691 = 8649848
211 + 8649637 = 8649848
331 + 8649517 = 8649848
379 + 8649469 = 8649848
397 + 8649451 = 8649848
439 + 8649409 = 8649848
457 + 8649391 = 8649848

Showing the first eight; more decompositions exist.
