Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533528, here are decompositions:

11 + 31533517 = 31533528
17 + 31533511 = 31533528
29 + 31533499 = 31533528
31 + 31533497 = 31533528
67 + 31533461 = 31533528
79 + 31533449 = 31533528
97 + 31533431 = 31533528
139 + 31533389 = 31533528

Showing the first eight; more decompositions exist.
