Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721334, here are decompositions:

5 + 8721329 = 8721334
23 + 8721311 = 8721334
53 + 8721281 = 8721334
137 + 8721197 = 8721334
233 + 8721101 = 8721334
257 + 8721077 = 8721334
443 + 8720891 = 8721334
563 + 8720771 = 8721334

Showing the first eight; more decompositions exist.
