Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543036, here are decompositions:

17 + 31543019 = 31543036
179 + 31542857 = 31543036
227 + 31542809 = 31543036
269 + 31542767 = 31543036
359 + 31542677 = 31543036
449 + 31542587 = 31543036
557 + 31542479 = 31543036
599 + 31542437 = 31543036

Showing the first eight; more decompositions exist.
