Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729982, here are decompositions:

5 + 8729977 = 8729982
43 + 8729939 = 8729982
59 + 8729923 = 8729982
101 + 8729881 = 8729982
113 + 8729869 = 8729982
181 + 8729801 = 8729982
271 + 8729711 = 8729982
293 + 8729689 = 8729982

Showing the first eight; more decompositions exist.
