Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668448, here are decompositions:

67 + 8668381 = 8668448
79 + 8668369 = 8668448
181 + 8668267 = 8668448
241 + 8668207 = 8668448
307 + 8668141 = 8668448
337 + 8668111 = 8668448
367 + 8668081 = 8668448
487 + 8667961 = 8668448

Showing the first eight; more decompositions exist.
