Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722406, here are decompositions:

13 + 8722393 = 8722406
67 + 8722339 = 8722406
73 + 8722333 = 8722406
103 + 8722303 = 8722406
109 + 8722297 = 8722406
283 + 8722123 = 8722406
307 + 8722099 = 8722406
313 + 8722093 = 8722406

Showing the first eight; more decompositions exist.
