Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722266, here are decompositions:

29 + 8722237 = 8722266
43 + 8722223 = 8722266
73 + 8722193 = 8722266
79 + 8722187 = 8722266
97 + 8722169 = 8722266
149 + 8722117 = 8722266
167 + 8722099 = 8722266
173 + 8722093 = 8722266

Showing the first eight; more decompositions exist.
