Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722508, here are decompositions:

31 + 8722477 = 8722508
37 + 8722471 = 8722508
61 + 8722447 = 8722508
79 + 8722429 = 8722508
211 + 8722297 = 8722508
271 + 8722237 = 8722508
337 + 8722171 = 8722508
409 + 8722099 = 8722508

Showing the first eight; more decompositions exist.
