Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681538, here are decompositions:

31 + 8681507 = 8681538
71 + 8681467 = 8681538
109 + 8681429 = 8681538
137 + 8681401 = 8681538
179 + 8681359 = 8681538
181 + 8681357 = 8681538
197 + 8681341 = 8681538
227 + 8681311 = 8681538

Showing the first eight; more decompositions exist.
