Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729850, here are decompositions:

11 + 8729839 = 8729850
13 + 8729837 = 8729850
29 + 8729821 = 8729850
83 + 8729767 = 8729850
139 + 8729711 = 8729850
191 + 8729659 = 8729850
229 + 8729621 = 8729850
257 + 8729593 = 8729850

Showing the first eight; more decompositions exist.
