Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649974, here are decompositions:

7 + 8649967 = 8649974
37 + 8649937 = 8649974
103 + 8649871 = 8649974
127 + 8649847 = 8649974
181 + 8649793 = 8649974
211 + 8649763 = 8649974
271 + 8649703 = 8649974
283 + 8649691 = 8649974

Showing the first eight; more decompositions exist.
