Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31534508, here are decompositions:

7 + 31534501 = 31534508
67 + 31534441 = 31534508
79 + 31534429 = 31534508
97 + 31534411 = 31534508
139 + 31534369 = 31534508
211 + 31534297 = 31534508
277 + 31534231 = 31534508
367 + 31534141 = 31534508

Showing the first eight; more decompositions exist.
