Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8666982, here are decompositions:

29 + 8666953 = 8666982
43 + 8666939 = 8666982
101 + 8666881 = 8666982
173 + 8666809 = 8666982
199 + 8666783 = 8666982
271 + 8666711 = 8666982
439 + 8666543 = 8666982
449 + 8666533 = 8666982

Showing the first eight; more decompositions exist.
