Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722360, here are decompositions:

29 + 8722331 = 8722360
137 + 8722223 = 8722360
149 + 8722211 = 8722360
167 + 8722193 = 8722360
173 + 8722187 = 8722360
191 + 8722169 = 8722360
263 + 8722097 = 8722360
281 + 8722079 = 8722360

Showing the first eight; more decompositions exist.
