Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543706, here are decompositions:

37 + 31543669 = 31543706
127 + 31543579 = 31543706
163 + 31543543 = 31543706
277 + 31543429 = 31543706
433 + 31543273 = 31543706
463 + 31543243 = 31543706
487 + 31543219 = 31543706
499 + 31543207 = 31543706

Showing the first eight; more decompositions exist.
