Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8680278, here are decompositions:

11 + 8680267 = 8680278
29 + 8680249 = 8680278
59 + 8680219 = 8680278
107 + 8680171 = 8680278
157 + 8680121 = 8680278
179 + 8680099 = 8680278
241 + 8680037 = 8680278
251 + 8680027 = 8680278

Showing the first eight; more decompositions exist.
