Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8681996, here are decompositions:

7 + 8681989 = 8681996
19 + 8681977 = 8681996
73 + 8681923 = 8681996
97 + 8681899 = 8681996
139 + 8681857 = 8681996
373 + 8681623 = 8681996
409 + 8681587 = 8681996
457 + 8681539 = 8681996

Showing the first eight; more decompositions exist.
