Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729252, here are decompositions:

3 + 8729249 = 8729252
13 + 8729239 = 8729252
31 + 8729221 = 8729252
61 + 8729191 = 8729252
73 + 8729179 = 8729252
79 + 8729173 = 8729252
193 + 8729059 = 8729252
199 + 8729053 = 8729252

Showing the first eight; more decompositions exist.
