Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 8722422, here are decompositions:

13 + 8722409 = 8722422
29 + 8722393 = 8722422
31 + 8722391 = 8722422
61 + 8722361 = 8722422
83 + 8722339 = 8722422
89 + 8722333 = 8722422
131 + 8722291 = 8722422
139 + 8722283 = 8722422

Showing the first eight; more decompositions exist.
