Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8678982, here are decompositions:

19 + 8678963 = 8678982
31 + 8678951 = 8678982
41 + 8678941 = 8678982
43 + 8678939 = 8678982
79 + 8678903 = 8678982
83 + 8678899 = 8678982
89 + 8678893 = 8678982
131 + 8678851 = 8678982

Showing the first eight; more decompositions exist.
