Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543794, here are decompositions:

11 + 31543783 = 31543794
17 + 31543777 = 31543794
31 + 31543763 = 31543794
43 + 31543751 = 31543794
71 + 31543723 = 31543794
83 + 31543711 = 31543794
97 + 31543697 = 31543794
103 + 31543691 = 31543794

Showing the first eight; more decompositions exist.
