Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649950, here are decompositions:

13 + 8649937 = 8649950
79 + 8649871 = 8649950
97 + 8649853 = 8649950
103 + 8649847 = 8649950
157 + 8649793 = 8649950
193 + 8649757 = 8649950
229 + 8649721 = 8649950
313 + 8649637 = 8649950

Showing the first eight; more decompositions exist.
