Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668254, here are decompositions:

47 + 8668207 = 8668254
53 + 8668201 = 8668254
61 + 8668193 = 8668254
97 + 8668157 = 8668254
103 + 8668151 = 8668254
113 + 8668141 = 8668254
173 + 8668081 = 8668254
181 + 8668073 = 8668254

Showing the first eight; more decompositions exist.
