Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543256, here are decompositions:

13 + 31543243 = 31543256
37 + 31543219 = 31543256
307 + 31542949 = 31543256
313 + 31542943 = 31543256
379 + 31542877 = 31543256
457 + 31542799 = 31543256
643 + 31542613 = 31543256
709 + 31542547 = 31543256

Showing the first eight; more decompositions exist.
