Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8634540, here are decompositions:

23 + 8634517 = 8634540
37 + 8634503 = 8634540
43 + 8634497 = 8634540
59 + 8634481 = 8634540
71 + 8634469 = 8634540
73 + 8634467 = 8634540
113 + 8634427 = 8634540
127 + 8634413 = 8634540

Showing the first eight; more decompositions exist.
