Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563364, here are decompositions:

5 + 31563359 = 31563364
17 + 31563347 = 31563364
227 + 31563137 = 31563364
233 + 31563131 = 31563364
383 + 31562981 = 31563364
563 + 31562801 = 31563364
587 + 31562777 = 31563364
653 + 31562711 = 31563364

Showing the first eight; more decompositions exist.
