Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668268, here are decompositions:

61 + 8668207 = 8668268
67 + 8668201 = 8668268
127 + 8668141 = 8668268
157 + 8668111 = 8668268
211 + 8668057 = 8668268
307 + 8667961 = 8668268
337 + 8667931 = 8668268
397 + 8667871 = 8668268

Showing the first eight; more decompositions exist.
