Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729760, here are decompositions:

31 + 8729729 = 8729760
43 + 8729717 = 8729760
71 + 8729689 = 8729760
79 + 8729681 = 8729760
101 + 8729659 = 8729760
113 + 8729647 = 8729760
131 + 8729629 = 8729760
139 + 8729621 = 8729760

Showing the first eight; more decompositions exist.
