Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563622, here are decompositions:

29 + 31563593 = 31563622
53 + 31563569 = 31563622
71 + 31563551 = 31563622
131 + 31563491 = 31563622
179 + 31563443 = 31563622
191 + 31563431 = 31563622
263 + 31563359 = 31563622
353 + 31563269 = 31563622

Showing the first eight; more decompositions exist.
