Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8621322, here are decompositions:

13 + 8621309 = 8621322
23 + 8621299 = 8621322
41 + 8621281 = 8621322
79 + 8621243 = 8621322
109 + 8621213 = 8621322
113 + 8621209 = 8621322
139 + 8621183 = 8621322
179 + 8621143 = 8621322

Showing the first eight; more decompositions exist.
