Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8743918, here are decompositions:

5 + 8743913 = 8743918
17 + 8743901 = 8743918
101 + 8743817 = 8743918
149 + 8743769 = 8743918
347 + 8743571 = 8743918
419 + 8743499 = 8743918
509 + 8743409 = 8743918
569 + 8743349 = 8743918

Showing the first eight; more decompositions exist.
