Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729972, here are decompositions:

103 + 8729869 = 8729972
151 + 8729821 = 8729972
283 + 8729689 = 8729972
313 + 8729659 = 8729972
331 + 8729641 = 8729972
379 + 8729593 = 8729972
409 + 8729563 = 8729972
571 + 8729401 = 8729972

Showing the first eight; more decompositions exist.
