Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722192, here are decompositions:

5 + 8722187 = 8722192
23 + 8722169 = 8722192
113 + 8722079 = 8722192
173 + 8722019 = 8722192
191 + 8722001 = 8722192
251 + 8721941 = 8722192
263 + 8721929 = 8722192
419 + 8721773 = 8722192

Showing the first eight; more decompositions exist.
