Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722204, here are decompositions:

11 + 8722193 = 8722204
17 + 8722187 = 8722204
107 + 8722097 = 8722204
263 + 8721941 = 8722204
353 + 8721851 = 8722204
431 + 8721773 = 8722204
467 + 8721737 = 8722204
503 + 8721701 = 8722204

Showing the first eight; more decompositions exist.
