Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681954, here are decompositions:

13 + 8681941 = 8681954
31 + 8681923 = 8681954
97 + 8681857 = 8681954
103 + 8681851 = 8681954
223 + 8681731 = 8681954
331 + 8681623 = 8681954
367 + 8681587 = 8681954
487 + 8681467 = 8681954

Showing the first eight; more decompositions exist.
