Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532532, here are decompositions:

11 + 31532521 = 31532532
43 + 31532489 = 31532532
103 + 31532429 = 31532532
131 + 31532401 = 31532532
179 + 31532353 = 31532532
191 + 31532341 = 31532532
193 + 31532339 = 31532532
263 + 31532269 = 31532532

Showing the first eight; more decompositions exist.
