Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729648, here are decompositions:

7 + 8729641 = 8729648
19 + 8729629 = 8729648
157 + 8729491 = 8729648
181 + 8729467 = 8729648
331 + 8729317 = 8729648
409 + 8729239 = 8729648
457 + 8729191 = 8729648
541 + 8729107 = 8729648

Showing the first eight; more decompositions exist.
