Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722822, here are decompositions:

23 + 8722799 = 8722822
83 + 8722739 = 8722822
149 + 8722673 = 8722822
179 + 8722643 = 8722822
191 + 8722631 = 8722822
281 + 8722541 = 8722822
431 + 8722391 = 8722822
461 + 8722361 = 8722822

Showing the first eight; more decompositions exist.
