Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721496, here are decompositions:

23 + 8721473 = 8721496
29 + 8721467 = 8721496
53 + 8721443 = 8721496
83 + 8721413 = 8721496
137 + 8721359 = 8721496
167 + 8721329 = 8721496
197 + 8721299 = 8721496
227 + 8721269 = 8721496

Showing the first eight; more decompositions exist.
