Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722202, here are decompositions:

31 + 8722171 = 8722202
79 + 8722123 = 8722202
103 + 8722099 = 8722202
109 + 8722093 = 8722202
193 + 8722009 = 8722202
439 + 8721763 = 8722202
571 + 8721631 = 8722202
661 + 8721541 = 8722202

Showing the first eight; more decompositions exist.
