Goldbach decomposition

Goldbach's conjecture says every even integer greater than 2 is the sum of two primes. For 31532768, here are decompositions:

19 + 31532749 = 31532768
31 + 31532737 = 31532768
109 + 31532659 = 31532768
181 + 31532587 = 31532768
229 + 31532539 = 31532768
271 + 31532497 = 31532768
331 + 31532437 = 31532768
367 + 31532401 = 31532768

Showing the first eight; more decompositions exist.
