Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563262, here are decompositions:

41 + 31563221 = 31563262
53 + 31563209 = 31563262
113 + 31563149 = 31563262
131 + 31563131 = 31563262
173 + 31563089 = 31563262
233 + 31563029 = 31563262
281 + 31562981 = 31563262
461 + 31562801 = 31563262

Showing the first eight; more decompositions exist.
