Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681846, here are decompositions:

67 + 8681779 = 8681846
109 + 8681737 = 8681846
139 + 8681707 = 8681846
223 + 8681623 = 8681846
307 + 8681539 = 8681846
373 + 8681473 = 8681846
379 + 8681467 = 8681846
487 + 8681359 = 8681846

Showing the first eight; more decompositions exist.
