Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649174, here are decompositions:

71 + 8649103 = 8649174
103 + 8649071 = 8649174
113 + 8649061 = 8649174
151 + 8649023 = 8649174
173 + 8649001 = 8649174
251 + 8648923 = 8649174
293 + 8648881 = 8649174
307 + 8648867 = 8649174

Showing the first eight; more decompositions exist.
