Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722644, here are decompositions:

13 + 8722631 = 8722644
23 + 8722621 = 8722644
31 + 8722613 = 8722644
37 + 8722607 = 8722644
41 + 8722603 = 8722644
103 + 8722541 = 8722644
127 + 8722517 = 8722644
167 + 8722477 = 8722644

Showing the first eight; more decompositions exist.
