Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543436, here are decompositions:

7 + 31543429 = 31543436
163 + 31543273 = 31543436
193 + 31543243 = 31543436
229 + 31543207 = 31543436
367 + 31543069 = 31543436
487 + 31542949 = 31543436
499 + 31542937 = 31543436
607 + 31542829 = 31543436

Showing the first eight; more decompositions exist.
