Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569716, here are decompositions:

7 + 31569709 = 31569716
103 + 31569613 = 31569716
337 + 31569379 = 31569716
349 + 31569367 = 31569716
379 + 31569337 = 31569716
397 + 31569319 = 31569716
439 + 31569277 = 31569716
457 + 31569259 = 31569716

Showing the first eight; more decompositions exist.
