Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532484, here are decompositions:

7 + 31532477 = 31532484
47 + 31532437 = 31532484
83 + 31532401 = 31532484
131 + 31532353 = 31532484
223 + 31532261 = 31532484
257 + 31532227 = 31532484
281 + 31532203 = 31532484
317 + 31532167 = 31532484

Showing the first eight; more decompositions exist.
