Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8638322, here are decompositions:

3 + 8638319 = 8638322
31 + 8638291 = 8638322
103 + 8638219 = 8638322
109 + 8638213 = 8638322
139 + 8638183 = 8638322
271 + 8638051 = 8638322
283 + 8638039 = 8638322
331 + 8637991 = 8638322

Showing the first eight; more decompositions exist.
