Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31533534, here are decompositions:

17 + 31533517 = 31533534
23 + 31533511 = 31533534
37 + 31533497 = 31533534
73 + 31533461 = 31533534
83 + 31533451 = 31533534
103 + 31533431 = 31533534
163 + 31533371 = 31533534
191 + 31533343 = 31533534

Showing the first eight; more decompositions exist.
