Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729960, here are decompositions:

37 + 8729923 = 8729960
73 + 8729887 = 8729960
79 + 8729881 = 8729960
139 + 8729821 = 8729960
193 + 8729767 = 8729960
271 + 8729689 = 8729960
313 + 8729647 = 8729960
331 + 8729629 = 8729960

Showing the first eight; more decompositions exist.
