Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8668418, here are decompositions:

37 + 8668381 = 8668418
61 + 8668357 = 8668418
139 + 8668279 = 8668418
151 + 8668267 = 8668418
211 + 8668207 = 8668418
277 + 8668141 = 8668418
307 + 8668111 = 8668418
337 + 8668081 = 8668418

Showing the first eight; more decompositions exist.
