Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533994, here are decompositions:

71 + 31533923 = 31533994
83 + 31533911 = 31533994
353 + 31533641 = 31533994
383 + 31533611 = 31533994
431 + 31533563 = 31533994
461 + 31533533 = 31533994
563 + 31533431 = 31533994
827 + 31533167 = 31533994

Showing the first eight; more decompositions exist.
