Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681738, here are decompositions:

7 + 8681731 = 8681738
31 + 8681707 = 8681738
151 + 8681587 = 8681738
199 + 8681539 = 8681738
271 + 8681467 = 8681738
337 + 8681401 = 8681738
379 + 8681359 = 8681738
397 + 8681341 = 8681738

Showing the first eight; more decompositions exist.
