Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543946, here are decompositions:

19 + 31543927 = 31543946
43 + 31543903 = 31543946
73 + 31543873 = 31543946
103 + 31543843 = 31543946
163 + 31543783 = 31543946
223 + 31543723 = 31543946
277 + 31543669 = 31543946
367 + 31543579 = 31543946

Showing the first eight; more decompositions exist.
