Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532852, here are decompositions:

19 + 31532833 = 31532852
103 + 31532749 = 31532852
193 + 31532659 = 31532852
199 + 31532653 = 31532852
271 + 31532581 = 31532852
313 + 31532539 = 31532852
331 + 31532521 = 31532852
499 + 31532353 = 31532852

Showing the first eight; more decompositions exist.
