Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8721322, here are decompositions:

11 + 8721311 = 8721322
23 + 8721299 = 8721322
41 + 8721281 = 8721322
53 + 8721269 = 8721322
83 + 8721239 = 8721322
131 + 8721191 = 8721322
293 + 8721029 = 8721322
353 + 8720969 = 8721322

Showing the first eight; more decompositions exist.
