Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722466, here are decompositions:

7 + 8722459 = 8722466
19 + 8722447 = 8722466
37 + 8722429 = 8722466
43 + 8722423 = 8722466
73 + 8722393 = 8722466
127 + 8722339 = 8722466
163 + 8722303 = 8722466
229 + 8722237 = 8722466

Showing the first eight; more decompositions exist.
