Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722416, here are decompositions:

7 + 8722409 = 8722416
23 + 8722393 = 8722416
83 + 8722333 = 8722416
113 + 8722303 = 8722416
179 + 8722237 = 8722416
193 + 8722223 = 8722416
223 + 8722193 = 8722416
229 + 8722187 = 8722416

Showing the first eight; more decompositions exist.
