Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649722, here are decompositions:

19 + 8649703 = 8649722
31 + 8649691 = 8649722
61 + 8649661 = 8649722
271 + 8649451 = 8649722
313 + 8649409 = 8649722
331 + 8649391 = 8649722
373 + 8649349 = 8649722
379 + 8649343 = 8649722

Showing the first eight; more decompositions exist.
