Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31589568, here are decompositions:

7 + 31589561 = 31589568
29 + 31589539 = 31589568
107 + 31589461 = 31589568
167 + 31589401 = 31589568
191 + 31589377 = 31589568
229 + 31589339 = 31589568
239 + 31589329 = 31589568
251 + 31589317 = 31589568

Showing the first eight; more decompositions exist.
