Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543670, here are decompositions:

127 + 31543543 = 31543670
139 + 31543531 = 31543670
181 + 31543489 = 31543670
241 + 31543429 = 31543670
397 + 31543273 = 31543670
439 + 31543231 = 31543670
463 + 31543207 = 31543670
601 + 31543069 = 31543670

Showing the first eight; more decompositions exist.
