Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543734, here are decompositions:

11 + 31543723 = 31543734
23 + 31543711 = 31543734
37 + 31543697 = 31543734
43 + 31543691 = 31543734
73 + 31543661 = 31543734
163 + 31543571 = 31543734
191 + 31543543 = 31543734
281 + 31543453 = 31543734

Showing the first eight; more decompositions exist.
