Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681654, here are decompositions:

31 + 8681623 = 8681654
67 + 8681587 = 8681654
151 + 8681503 = 8681654
181 + 8681473 = 8681654
277 + 8681377 = 8681654
313 + 8681341 = 8681654
337 + 8681317 = 8681654
367 + 8681287 = 8681654

Showing the first eight; more decompositions exist.
