Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8627918, here are decompositions:

7 + 8627911 = 8627918
67 + 8627851 = 8627918
109 + 8627809 = 8627918
307 + 8627611 = 8627918
337 + 8627581 = 8627918
349 + 8627569 = 8627918
421 + 8627497 = 8627918
487 + 8627431 = 8627918

Showing the first eight; more decompositions exist.
