Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722154, here are decompositions:

31 + 8722123 = 8722154
37 + 8722117 = 8722154
61 + 8722093 = 8722154
73 + 8722081 = 8722154
127 + 8722027 = 8722154
157 + 8721997 = 8722154
241 + 8721913 = 8722154
271 + 8721883 = 8722154

Showing the first eight; more decompositions exist.
