Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533462, here are decompositions:

11 + 31533451 = 31533462
13 + 31533449 = 31533462
31 + 31533431 = 31533462
53 + 31533409 = 31533462
73 + 31533389 = 31533462
83 + 31533379 = 31533462
193 + 31533269 = 31533462
271 + 31533191 = 31533462

Showing the first eight; more decompositions exist.
