Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721466, here are decompositions:

23 + 8721443 = 8721466
53 + 8721413 = 8721466
107 + 8721359 = 8721466
137 + 8721329 = 8721466
167 + 8721299 = 8721466
197 + 8721269 = 8721466
227 + 8721239 = 8721466
269 + 8721197 = 8721466

Showing the first eight; more decompositions exist.
