Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721526, here are decompositions:

53 + 8721473 = 8721526
59 + 8721467 = 8721526
83 + 8721443 = 8721526
113 + 8721413 = 8721526
167 + 8721359 = 8721526
197 + 8721329 = 8721526
227 + 8721299 = 8721526
257 + 8721269 = 8721526

Showing the first eight; more decompositions exist.
