Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722260, here are decompositions:

23 + 8722237 = 8722260
37 + 8722223 = 8722260
67 + 8722193 = 8722260
73 + 8722187 = 8722260
89 + 8722171 = 8722260
137 + 8722123 = 8722260
163 + 8722097 = 8722260
167 + 8722093 = 8722260

Showing the first eight; more decompositions exist.
