Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8718406, here are decompositions:

5 + 8718401 = 8718406
29 + 8718377 = 8718406
293 + 8718113 = 8718406
317 + 8718089 = 8718406
419 + 8717987 = 8718406
443 + 8717963 = 8718406
467 + 8717939 = 8718406
479 + 8717927 = 8718406

Showing the first eight; more decompositions exist.
