Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722916, here are decompositions:

3 + 8722913 = 8722916
127 + 8722789 = 8722916
313 + 8722603 = 8722916
439 + 8722477 = 8722916
457 + 8722459 = 8722916
487 + 8722429 = 8722916
523 + 8722393 = 8722916
577 + 8722339 = 8722916

Showing the first eight; more decompositions exist.
