Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729694, here are decompositions:

5 + 8729689 = 8729694
13 + 8729681 = 8729694
47 + 8729647 = 8729694
53 + 8729641 = 8729694
73 + 8729621 = 8729694
101 + 8729593 = 8729694
131 + 8729563 = 8729694
137 + 8729557 = 8729694

Showing the first eight; more decompositions exist.
