Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8649126, here are decompositions:

23 + 8649103 = 8649126
47 + 8649079 = 8649126
97 + 8649029 = 8649126
103 + 8649023 = 8649126
173 + 8648953 = 8649126
197 + 8648929 = 8649126
263 + 8648863 = 8649126
293 + 8648833 = 8649126

Showing the first eight; more decompositions exist.
