Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729308, here are decompositions:

17 + 8729291 = 8729308
59 + 8729249 = 8729308
89 + 8729219 = 8729308
101 + 8729207 = 8729308
167 + 8729141 = 8729308
191 + 8729117 = 8729308
227 + 8729081 = 8729308
251 + 8729057 = 8729308

Showing the first eight; more decompositions exist.
