Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532968, here are decompositions:

29 + 31532939 = 31532968
101 + 31532867 = 31532968
191 + 31532777 = 31532968
281 + 31532687 = 31532968
461 + 31532507 = 31532968
479 + 31532489 = 31532968
491 + 31532477 = 31532968
827 + 31532141 = 31532968

Showing the first eight; more decompositions exist.
