Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533484, here are decompositions:

23 + 31533461 = 31533484
53 + 31533431 = 31533484
71 + 31533413 = 31533484
113 + 31533371 = 31533484
293 + 31533191 = 31533484
317 + 31533167 = 31533484
383 + 31533101 = 31533484
503 + 31532981 = 31533484

Showing the first eight; more decompositions exist.
