Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722626, here are decompositions:

5 + 8722621 = 8722626
13 + 8722613 = 8722626
19 + 8722607 = 8722626
23 + 8722603 = 8722626
109 + 8722517 = 8722626
127 + 8722499 = 8722626
149 + 8722477 = 8722626
167 + 8722459 = 8722626

Showing the first eight; more decompositions exist.
