Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718418, here are decompositions:

11 + 8718407 = 8718418
17 + 8718401 = 8718418
41 + 8718377 = 8718418
167 + 8718251 = 8718418
197 + 8718221 = 8718418
227 + 8718191 = 8718418
419 + 8717999 = 8718418
431 + 8717987 = 8718418

Showing the first eight; more decompositions exist.
