Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8661982, here are decompositions:

5 + 8661977 = 8661982
29 + 8661953 = 8661982
41 + 8661941 = 8661982
83 + 8661899 = 8661982
101 + 8661881 = 8661982
239 + 8661743 = 8661982
293 + 8661689 = 8661982
353 + 8661629 = 8661982

Showing the first eight; more decompositions exist.
