Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722244, here are decompositions:

7 + 8722237 = 8722244
73 + 8722171 = 8722244
127 + 8722117 = 8722244
151 + 8722093 = 8722244
163 + 8722081 = 8722244
211 + 8722033 = 8722244
331 + 8721913 = 8722244
337 + 8721907 = 8722244

Showing the first eight; more decompositions exist.
