Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729288, here are decompositions:

67 + 8729221 = 8729288
97 + 8729191 = 8729288
109 + 8729179 = 8729288
157 + 8729131 = 8729288
181 + 8729107 = 8729288
229 + 8729059 = 8729288
367 + 8728921 = 8729288
439 + 8728849 = 8729288

Showing the first eight; more decompositions exist.
