Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722636, here are decompositions:

5 + 8722631 = 8722636
23 + 8722613 = 8722636
29 + 8722607 = 8722636
137 + 8722499 = 8722636
227 + 8722409 = 8722636
269 + 8722367 = 8722636
353 + 8722283 = 8722636
443 + 8722193 = 8722636

Showing the first eight; more decompositions exist.
