Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722308, here are decompositions:

5 + 8722303 = 8722308
11 + 8722297 = 8722308
17 + 8722291 = 8722308
71 + 8722237 = 8722308
97 + 8722211 = 8722308
137 + 8722171 = 8722308
139 + 8722169 = 8722308
191 + 8722117 = 8722308

Showing the first eight; more decompositions exist.
