Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8729322, here are decompositions:

5 + 8729317 = 8729322
13 + 8729309 = 8729322
31 + 8729291 = 8729322
73 + 8729249 = 8729322
79 + 8729243 = 8729322
83 + 8729239 = 8729322
101 + 8729221 = 8729322
103 + 8729219 = 8729322

Showing the first eight; more decompositions exist.
