Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722210, here are decompositions:

17 + 8722193 = 8722210
23 + 8722187 = 8722210
41 + 8722169 = 8722210
113 + 8722097 = 8722210
131 + 8722079 = 8722210
191 + 8722019 = 8722210
269 + 8721941 = 8722210
281 + 8721929 = 8722210

Showing the first eight; more decompositions exist.
