Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729748, here are decompositions:

19 + 8729729 = 8729748
31 + 8729717 = 8729748
37 + 8729711 = 8729748
59 + 8729689 = 8729748
67 + 8729681 = 8729748
89 + 8729659 = 8729748
101 + 8729647 = 8729748
107 + 8729641 = 8729748

Showing the first eight; more decompositions exist.
