Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729924, here are decompositions:

37 + 8729887 = 8729924
43 + 8729881 = 8729924
103 + 8729821 = 8729924
157 + 8729767 = 8729924
277 + 8729647 = 8729924
283 + 8729641 = 8729924
331 + 8729593 = 8729924
367 + 8729557 = 8729924

Showing the first eight; more decompositions exist.
