Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722194, here are decompositions:

7 + 8722187 = 8722194
23 + 8722171 = 8722194
71 + 8722123 = 8722194
97 + 8722097 = 8722194
101 + 8722093 = 8722194
113 + 8722081 = 8722194
167 + 8722027 = 8722194
193 + 8722001 = 8722194

Showing the first eight; more decompositions exist.
