Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31569582, here are decompositions:

13 + 31569569 = 31569582
101 + 31569481 = 31569582
103 + 31569479 = 31569582
223 + 31569359 = 31569582
263 + 31569319 = 31569582
281 + 31569301 = 31569582
349 + 31569233 = 31569582
353 + 31569229 = 31569582

Showing the first eight; more decompositions exist.
