Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668248, here are decompositions:

41 + 8668207 = 8668248
47 + 8668201 = 8668248
97 + 8668151 = 8668248
107 + 8668141 = 8668248
137 + 8668111 = 8668248
167 + 8668081 = 8668248
181 + 8668067 = 8668248
191 + 8668057 = 8668248

Showing the first eight; more decompositions exist.
