Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31543496, here are decompositions:

7 + 31543489 = 31543496
43 + 31543453 = 31543496
67 + 31543429 = 31543496
223 + 31543273 = 31543496
277 + 31543219 = 31543496
487 + 31543009 = 31543496
547 + 31542949 = 31543496
619 + 31542877 = 31543496

Showing the first eight; more decompositions exist.
