Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8749018, here are decompositions:

11 + 8749007 = 8749018
17 + 8749001 = 8749018
29 + 8748989 = 8749018
137 + 8748881 = 8749018
191 + 8748827 = 8749018
197 + 8748821 = 8749018
251 + 8748767 = 8749018
419 + 8748599 = 8749018

Showing the first eight; more decompositions exist.
