Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722126, here are decompositions:

3 + 8722123 = 8722126
29 + 8722097 = 8722126
47 + 8722079 = 8722126
107 + 8722019 = 8722126
137 + 8721989 = 8722126
197 + 8721929 = 8722126
353 + 8721773 = 8722126
389 + 8721737 = 8722126

Showing the first eight; more decompositions exist.
