Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719528, here are decompositions:

107 + 8719421 = 8719528
137 + 8719391 = 8719528
149 + 8719379 = 8719528
179 + 8719349 = 8719528
227 + 8719301 = 8719528
239 + 8719289 = 8719528
317 + 8719211 = 8719528
401 + 8719127 = 8719528

Showing the first eight; more decompositions exist.
