Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721352, here are decompositions:

23 + 8721329 = 8721352
41 + 8721311 = 8721352
53 + 8721299 = 8721352
71 + 8721281 = 8721352
83 + 8721269 = 8721352
113 + 8721239 = 8721352
251 + 8721101 = 8721352
383 + 8720969 = 8721352

Showing the first eight; more decompositions exist.
