Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533550, here are decompositions:

3 + 31533547 = 31533550
17 + 31533533 = 31533550
53 + 31533497 = 31533550
89 + 31533461 = 31533550
101 + 31533449 = 31533550
137 + 31533413 = 31533550
179 + 31533371 = 31533550
281 + 31533269 = 31533550

Showing the first eight; more decompositions exist.
