Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563592, here are decompositions:

23 + 31563569 = 31563592
41 + 31563551 = 31563592
101 + 31563491 = 31563592
149 + 31563443 = 31563592
191 + 31563401 = 31563592
233 + 31563359 = 31563592
383 + 31563209 = 31563592
443 + 31563149 = 31563592

Showing the first eight; more decompositions exist.
