Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563454, here are decompositions:

3 + 31563451 = 31563454
11 + 31563443 = 31563454
23 + 31563431 = 31563454
53 + 31563401 = 31563454
107 + 31563347 = 31563454
233 + 31563221 = 31563454
317 + 31563137 = 31563454
467 + 31562987 = 31563454

Showing the first eight; more decompositions exist.
