Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719540, here are decompositions:

149 + 8719391 = 8719540
173 + 8719367 = 8719540
191 + 8719349 = 8719540
233 + 8719307 = 8719540
239 + 8719301 = 8719540
251 + 8719289 = 8719540
317 + 8719223 = 8719540
353 + 8719187 = 8719540

Showing the first eight; more decompositions exist.
