Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543016, here are decompositions:

7 + 31543009 = 31543016
67 + 31542949 = 31543016
73 + 31542943 = 31543016
79 + 31542937 = 31543016
139 + 31542877 = 31543016
229 + 31542787 = 31543016
313 + 31542703 = 31543016
457 + 31542559 = 31543016

Showing the first eight; more decompositions exist.
