Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31563754, here are decompositions:

17 + 31563737 = 31563754
71 + 31563683 = 31563754
83 + 31563671 = 31563754
107 + 31563647 = 31563754
227 + 31563527 = 31563754
263 + 31563491 = 31563754
311 + 31563443 = 31563754
353 + 31563401 = 31563754

Showing the first eight; more decompositions exist.
