Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532516, here are decompositions:

19 + 31532497 = 31532516
79 + 31532437 = 31532516
163 + 31532353 = 31532516
193 + 31532323 = 31532516
307 + 31532209 = 31532516
313 + 31532203 = 31532516
349 + 31532167 = 31532516
607 + 31531909 = 31532516

Showing the first eight; more decompositions exist.
