Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729732, here are decompositions:

3 + 8729729 = 8729732
43 + 8729689 = 8729732
73 + 8729659 = 8729732
103 + 8729629 = 8729732
139 + 8729593 = 8729732
241 + 8729491 = 8729732
331 + 8729401 = 8729732
409 + 8729323 = 8729732

Showing the first eight; more decompositions exist.
