Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719618, here are decompositions:

41 + 8719577 = 8719618
197 + 8719421 = 8719618
227 + 8719391 = 8719618
239 + 8719379 = 8719618
251 + 8719367 = 8719618
269 + 8719349 = 8719618
311 + 8719307 = 8719618
317 + 8719301 = 8719618

Showing the first eight; more decompositions exist.
