Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532888, here are decompositions:

7 + 31532881 = 31532888
139 + 31532749 = 31532888
151 + 31532737 = 31532888
229 + 31532659 = 31532888
307 + 31532581 = 31532888
337 + 31532551 = 31532888
349 + 31532539 = 31532888
367 + 31532521 = 31532888

Showing the first eight; more decompositions exist.
