Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649168, here are decompositions:

89 + 8649079 = 8649168
97 + 8649071 = 8649168
107 + 8649061 = 8649168
139 + 8649029 = 8649168
167 + 8649001 = 8649168
239 + 8648929 = 8649168
331 + 8648837 = 8649168
337 + 8648831 = 8649168

Showing the first eight; more decompositions exist.
