Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722588, here are decompositions:

47 + 8722541 = 8722588
71 + 8722517 = 8722588
89 + 8722499 = 8722588
179 + 8722409 = 8722588
197 + 8722391 = 8722588
227 + 8722361 = 8722588
257 + 8722331 = 8722588
401 + 8722187 = 8722588

Showing the first eight; more decompositions exist.
