Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729772, here are decompositions:

5 + 8729767 = 8729772
43 + 8729729 = 8729772
61 + 8729711 = 8729772
83 + 8729689 = 8729772
113 + 8729659 = 8729772
131 + 8729641 = 8729772
151 + 8729621 = 8729772
179 + 8729593 = 8729772

Showing the first eight; more decompositions exist.
