Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729946, here are decompositions:

7 + 8729939 = 8729946
23 + 8729923 = 8729946
59 + 8729887 = 8729946
79 + 8729867 = 8729946
97 + 8729849 = 8729946
107 + 8729839 = 8729946
109 + 8729837 = 8729946
179 + 8729767 = 8729946

Showing the first eight; more decompositions exist.
