Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8746278, here are decompositions:

7 + 8746271 = 8746278
11 + 8746267 = 8746278
17 + 8746261 = 8746278
19 + 8746259 = 8746278
41 + 8746237 = 8746278
71 + 8746207 = 8746278
241 + 8746037 = 8746278
269 + 8746009 = 8746278

Showing the first eight; more decompositions exist.
