Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729744, here are decompositions:

97 + 8729647 = 8729744
103 + 8729641 = 8729744
151 + 8729593 = 8729744
181 + 8729563 = 8729744
277 + 8729467 = 8729744
421 + 8729323 = 8729744
523 + 8729221 = 8729744
571 + 8729173 = 8729744

Showing the first eight; more decompositions exist.
