Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729948, here are decompositions:

61 + 8729887 = 8729948
67 + 8729881 = 8729948
79 + 8729869 = 8729948
109 + 8729839 = 8729948
127 + 8729821 = 8729948
181 + 8729767 = 8729948
307 + 8729641 = 8729948
457 + 8729491 = 8729948

Showing the first eight; more decompositions exist.
