Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8691982, here are decompositions:

3 + 8691979 = 8691982
11 + 8691971 = 8691982
41 + 8691941 = 8691982
59 + 8691923 = 8691982
149 + 8691833 = 8691982
179 + 8691803 = 8691982
251 + 8691731 = 8691982
293 + 8691689 = 8691982

Showing the first eight; more decompositions exist.
