Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681974, here are decompositions:

5 + 8681969 = 8681974
17 + 8681957 = 8681974
137 + 8681837 = 8681974
281 + 8681693 = 8681974
311 + 8681663 = 8681974
461 + 8681513 = 8681974
467 + 8681507 = 8681974
491 + 8681483 = 8681974

Showing the first eight; more decompositions exist.
