Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31568732, here are decompositions:

31 + 31568701 = 31568732
103 + 31568629 = 31568732
193 + 31568539 = 31568732
241 + 31568491 = 31568732
313 + 31568419 = 31568732
379 + 31568353 = 31568732
421 + 31568311 = 31568732
661 + 31568071 = 31568732

Showing the first eight; more decompositions exist.
