Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668148, here are decompositions:

7 + 8668141 = 8668148
37 + 8668111 = 8668148
67 + 8668081 = 8668148
199 + 8667949 = 8668148
241 + 8667907 = 8668148
277 + 8667871 = 8668148
421 + 8667727 = 8668148
487 + 8667661 = 8668148

Showing the first eight; more decompositions exist.
