Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31527508, here are decompositions:

11 + 31527497 = 31527508
17 + 31527491 = 31527508
101 + 31527407 = 31527508
191 + 31527317 = 31527508
197 + 31527311 = 31527508
317 + 31527191 = 31527508
359 + 31527149 = 31527508
401 + 31527107 = 31527508

Showing the first eight; more decompositions exist.
