Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534568, here are decompositions:

7 + 31534561 = 31534568
67 + 31534501 = 31534568
127 + 31534441 = 31534568
139 + 31534429 = 31534568
157 + 31534411 = 31534568
199 + 31534369 = 31534568
271 + 31534297 = 31534568
337 + 31534231 = 31534568

Showing the first eight; more decompositions exist.
