Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8719426, here are decompositions:

5 + 8719421 = 8719426
47 + 8719379 = 8719426
59 + 8719367 = 8719426
137 + 8719289 = 8719426
173 + 8719253 = 8719426
227 + 8719199 = 8719426
239 + 8719187 = 8719426
263 + 8719163 = 8719426

Showing the first eight; more decompositions exist.
