Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563514, here are decompositions:

23 + 31563491 = 31563514
71 + 31563443 = 31563514
83 + 31563431 = 31563514
113 + 31563401 = 31563514
137 + 31563377 = 31563514
167 + 31563347 = 31563514
293 + 31563221 = 31563514
383 + 31563131 = 31563514

Showing the first eight; more decompositions exist.
