Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729976, here are decompositions:

37 + 8729939 = 8729976
53 + 8729923 = 8729976
89 + 8729887 = 8729976
107 + 8729869 = 8729976
109 + 8729867 = 8729976
127 + 8729849 = 8729976
137 + 8729839 = 8729976
139 + 8729837 = 8729976

Showing the first eight; more decompositions exist.
