Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729740, here are decompositions:

11 + 8729729 = 8729740
23 + 8729717 = 8729740
29 + 8729711 = 8729740
59 + 8729681 = 8729740
137 + 8729603 = 8729740
197 + 8729543 = 8729740
311 + 8729429 = 8729740
431 + 8729309 = 8729740

Showing the first eight; more decompositions exist.
