Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729168, here are decompositions:

37 + 8729131 = 8729168
61 + 8729107 = 8729168
109 + 8729059 = 8729168
181 + 8728987 = 8729168
199 + 8728969 = 8729168
241 + 8728927 = 8729168
271 + 8728897 = 8729168
457 + 8728711 = 8729168

Showing the first eight; more decompositions exist.
