Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722056, here are decompositions:

23 + 8722033 = 8722056
29 + 8722027 = 8722056
37 + 8722019 = 8722056
47 + 8722009 = 8722056
59 + 8721997 = 8722056
67 + 8721989 = 8722056
127 + 8721929 = 8722056
139 + 8721917 = 8722056

Showing the first eight; more decompositions exist.
