Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532514, here are decompositions:

7 + 31532507 = 31532514
17 + 31532497 = 31532514
37 + 31532477 = 31532514
113 + 31532401 = 31532514
173 + 31532341 = 31532514
191 + 31532323 = 31532514
311 + 31532203 = 31532514
347 + 31532167 = 31532514

Showing the first eight; more decompositions exist.
